I'm not that big fan of twitter and don't even like to visit there. But few days back I just visited there and opened an account. And tried to study the procedure of following people and how to make them follow me in higher % . Then I concentrated on how I can target them? Then Certainly I got success on that too. Now I am thinking of starting Twitter promotional tools business. but I have no Idea that how valuable twitter traffic has???? Any Idea???? Cheers.
