This is where Nimbuzz comes in really handy as it's a multi-platform instant messaging client. This enables you to chat with your contacts and keep track of your friends' updates on more than a dozen different social networks and IM protocols, including Facebook, Twitter, MySpace, MSN, ICQ, Google Talk and Jabber, among others.

Nimbuzz is already quite popular among mobile platforms, where it has been around for a while. This port to PC has gone a bit unnoticed, I guess partly because Nimbuzz doesn't feature as many tools and options as other similar programs. The tool in itself is quite simple, very light on resources and does what it says on the tin. There are no custom backgrounds, animation effects or any other bells and whistles.

Besides basic text chat, Nimbuzz includes other interesting options such as the ability to organize contacts by groups and the possibility to share files with them, even if they're not online, thanks a to a temporary storage system. Being primarily a mobile IM app, Nimbuzz also allows you to keep contacts synced with your mobile phone.

Despite being simpler than other similar tools, Nimbuzz is still a great app to keep in touch with friends across many different social networks and IM platforms.

QQ Messenger may not sound familiar, but it's the most popular IM client in China.

When you think about IM clients, the first names that come to your head are Windows Live Messenger, Yahoo! Messenger and the likes. But have you ever heard of QQ Messenger?

With more than one billion registered accounts, QQ Messenger is now more than just a simple IM client: it's a whole social phenomenon that millions of people use on a daily basis, and an essential part of their lives.

The truth is that QQ Messenger is not that different from other IM clients you may have used. There are the typical contacts list – which you can organize by groups - support for voice and video chats, smileys, nudges, ability to send photos and share files (with support for pause/resume!), and other utilities we're used to finding in IM clients. There's one important difference however: in QQ Messenger you hardly find any ads!

Besides the traditional IM tools, QQ Messenger also includes some not-so-common features. You'll be able to capture an area of your screen or record a short video clip on the spot, and share both of them instantly with your contacts. Another area where QQ Messenger stands out is personalization. You can customize almost anything, from choosing a skin for the interface to selecting the font for your messages. The program also includes a wide selection of avatars and personal pictures to choose from, but if you don't like any of them, simply upload one from your hard drive. The only thing that didn't work for us was downloading more themes from the Web.

QQ Messenger is mainly a tool for chat, but it can also be used to help your friends or customers thanks to its integrated Remote assistance tool: a basic remote control app that grants you access to your friend's desktop and enables you to help them with any computer issue.

In general terms, QQ Messenger surprised us for various reasons: first, it features a nicely designed interface with cute buttons and icons, which is hard to find in IM clients; second, it has interesting extra features that make it a complete communication tool; and third, it's amazing how such a popular program with more than a billion users is still known by so few people over here!

On the downside, I have to admit that QQ Messenger was a bit unreliable when trying to add contacts - which, by the way, are identified with numbers, like good old ICQ. Not a very user-friendly method, I'd say. Other than that, QQ Messenger is a great IM cilent that is definitely worth trying out.

QQ Messenger, the most widely used IM client in China, has now an international version that may help it become even more popular!

Trillian supports multiple chat networks, such as Live Messenger, AOL Messenger, Yahoo! Messenger, Google Talk, ICQ, Facebook, MySpaceIM, Skype, Jabber, IRC, Twitter, e-mail accounts (POP3 and IMAP) and Bonjour, besides the Trillian proprietary network.

This means that the program's interface can get quite bloated with contacts from a dozen different IM platforms. Luckily, you decide which networks to load on Trillian startup, and also temporarily hide certain lists or merge contacts into one single entry per person, which may help organize things a bit.

The new version of Trillian has improved many aspects of the program. Initial setting is now much quicker and easier, and the interface has totally been redesigned not only for a better integration with Windows 7, but also to provide you with a more compact, easily manageable window.

In a way, Trillian is not just a multi-platform instant messaging tool anymore, but a complete social timeline where you can chat with your friends – either by text, voice or video - and also see what they’re up to on Facebook or Twitter.

Trillian is back with an even more powerful mult-platform IM client, featuring support for a dozen protocols and an attractive, intuitive design.

To bring Yahoo! Messenger up to date, Facebook chat has been integrated into the latest version, along with social games like Mafia Wars. You can now use video chat in full-screen mode, and the 'Always On' feature means you'll stay connected whether on mobile, at home or at work.

You can of course update your Facebook status from Yahoo! Messenger, and also on Yahoo! What hasn't changed from the previous version is the amount of bloat in the app. Some people may appreciate the shared videos, social games (as shown in the video here), radio stations, emoticons, search bar and so on. However, all this stuff adds a lot of weight to the Yahoo! Messenger, and it feels unsophisticated today. The video call quality in Yahoo! Messenger is pretty good, however, and in fact if it stuck to being a chat app, we would recommend it more highly!

The amplification of social aspects in Yahoo! Messenger isn't a revolution. If you love all the bells and whistles, you'll love this app, but many people will find it annoying and intrusive.

Paltalk includes access to hundreds of chat rooms on a huge variety of topics, and has also support for audio and video chat. The number of chat rooms and video conferences you can join, however, depends on the plan you subscribe to, from the free Basic one with very limited features to the VIP plan for $29.95 a month.

The interface in Paltalk is very similar to that of other IM clients. You have a personal area on top of the window with your avatar and nickname, and then a list of contacts. The bottom part displays the list of available chat rooms. Paltalk can also be used as a standard client for other popular IM networks such as Messenger, Google Talk, AOL Messenger, Yahoo! Messenger, ICQ and the Facebook chat – as long as you install the necessary plug-ins.

An original feature in Paltalk is the creation of an online chat profile that you can share with your family and friends so that they can IM you at any time from their web browser, without having to install anything.

In general terms Paltalk feels a bit overwhelming because there are ads all over the place and more often than not, you enter a room only to hear music or ranting from a user. The messages exchanged in Paltalk's chat rooms are often so jumbled up that it's hard to be able to follow a genuine conversation.

Paltalk is a desktop IM client with support for audio and video chats, and with lots of chat rooms to meet people from all around the world.

Windows Live Messenger previously known as MSN Messenger, was renamed as part of Microsoft's move away from Hotmail, towards the Live online community. Now the most popular IM app in the world has finally reached version 2009.

Features

Windows Live Messenger offers plenty of emoticons and winks to cheer up your conversations. You can expand both collections easily by adding new sets which you'll find by the hundred on the Internet. Customization possibilities include changing the chat window background or even adding a personal message to your nickname, but not creating custom status messages. Also, Windows Live Messenger status messages have now been reduced to "online", "away" or "busy" – so no more "on the phone" or "out to lunch", for example.

Chat conversations are not the only thing you can do with Windows Live Messenger. There is also the possibility of having video chats using your webcam, and also make VoIP calls. Another great feature in Windows Live Messenger is the possibility to view and share pictures within the chat window, without having to send files over to your contact.

Regarding contact lists, the new Windows Live Messenger lets you create specific groups of users, different from the ones previously known as "groups" and which have now been renamed to Categories. These groups allow you to have multiple simultaneous chats with several contacts. Another new feature in the contact management system in Windows Live Messenger is Favorites, a special category that enables you to have the people you talk to most always to hand.

Usability

Windows Live Messenger 2009 includes many interesting new features, all conveniently built into a nice interface. I'm not sure that this handful of new functions is the reason why the program weighs in at almost 70 MB.

Quality

The most striking feature in the new Windows Live Messenger is an all-new interface with a colorful design, far from the traditional Windows application structure. You can customize it by choosing your own theme and color scheme.

In order to maintain the neatness of this design, the menu bar in Windows Live Messenger has been hidden under a few buttons on the top-right corner – though you can temporarily make the standard menu bar visible by pressing the Alt key. While I understand the reason why they did this, it makes menu options a bit uncomfortable to browse.

Conclusion

Windows Live Messenger reaches version 2009 with a renewed interface, loads of new features and a bit of extra weight.

Context

Windows Live Messenger will be discontinued on April 8. 2013.

Users will have to use Skype with imported contacts to continue messaging Windows Live Messenger contacts.

Available everywhere

Not only does Google Talk support Google accounts, it also supports a variety of other protocols and apps. In other words, you can log in with accounts from Jabber, Pidgin, Miranda, Psiand Trillian.

As well as supporting lots of protocols, Google Talk is also available for lots of devices, so even if you are chatting on your desktop, you'll be able to keep in touch with your friends on Android, iPhone and Blackberry. Even though not explicitly supported, you'll also be able to use Google Talk on Mac and Linux, as long as you use the browser version.

Simple but effective

Google Talk is an attractive app and very easy to use, although its bright, almost childlike appearance is looking a bit old-fashioned these days. There are various themes available from the Settings options, although they have more impact on the window layout and are not strictly "skins". You'll also be able to choose your status, picking from Available, Busy, and Idle, as well as custom messages and the option to show your current music track. Google Talk also notifies you when you receive new emails.

Adding and chatting with contacts with Google Talk couldn't be easier. Double click a name to start a conversation, and a new chat window will appear. If you see a little telephone or video camera icon beside the contact's name, they are also available for phone or video chats, but you'll need the Video and voice plug-in to do this.

Works, but it's neglected

Google Talk has many of the features that you'd expect from an IM client. You can add, block, rename and remove contacts, send smileys, and customize the way you see your friends online. If you look under the more technical settings, you'll also be able modify notifications and connect to the service using a proxy. It's not overrun with options, but most people seem to appreciate the resulting simplicity and light resource use.

Even though Google Talk is the go-to IM app for thousands of people, long term users can't help feeling that Google Talk is pretty low on Google's list of priorities. It works perfectly and is a great app, but that's because it was well made and ahead of its time when it first came out.

Overall

Google Talk hasn't been updated in what seems like years and, with the exception of the VoiP features added in recent times, the program feels a little bit forgotten. This has no impact on usability for Gmail users, but it does feel like Google Talk could do with a little more loving care.

If you're a Google User who wants to IM, you'd be mad to use anything but Google Talk.

IM applications are a great way to stay in touch with your friends. But what happens if they all use different networks? Either you choose one single network (therefore losing contact with all friends left outside) or you use a multi-network IM client like SIM.

This tool enables you to connect to multiple IM networks at the same time, displaying all your contacts on the same window. This is great when you have friends and family spread over different IM systems, as SIM offers support for the most popular ones: ICQ, MSN, Jabber, Yahoo! and more.

During our tests, however, the program seemed a bit unstable and it even crashed once. The interface and general design lines look very basic, as well as the functionality offered by the program.
