I assume you are a Tweeter. Tell me frankly mate, what exactly you are looking for in Twitter? Do you really believe your micro-blogging posts are read by your so-called ‘followers’.?
If so, other also might expect the same-right?
Tell me now, do you spend time to read the tweets of your followers or you just sue some automation tool to post your tweets and never bother to log into your Twitter account to read the tweets of your followers?
I now assume you are strongly saying that tweets are read by the followers. In that case, as a Tweeter, you must have more followers-eh?
http://www.followfollowers.com/ is a unique tool to manage your Twitter followers.
This tool is free and gives plenty of options to follow and unfollow Tweeters.
