What the community says about Karma
"Ever wanted more followers and more fun stuff on your twitter account look no further you found the twitter booster you were always looking for.""I tried it but my life is already too complicated. I do see how useful this can be for someone who is tweeting constantly."
"I wanted to be more popular on Twitter, so I tried to find some resources to help with getting some more Twitter mentions. In the process, I found a site called Karma. While it was a great and easy resource for managing my followers, it didn't help at all with my popularity.""While not a full blown Twitter client, Karma still provides a valuable service to those seeking to expand their twitter base and manage those who have stopped engaging. Best of all, it's free!"
"If you feel like there are just too many users that you have followed and never see them active or benefiting your site by not following or giving a chance to retweet, then you will definitely find Karma useful. You are able to easily unfollow anyone that hasn't followed you, and instantly follow those who are following you. It's pretty neat!""Great tool and i love that you can do this! Ithink most if not all tweeters will appreciate this option as a way to generate more tweets. I don't know if it will do what it says as sometimes the amount of tweets you get and are able to follow depends on your friens and followers. All in all i still believe this is great."
