Follow you where? On twitter? I'm sorry I guess I don't quite understand....nevertheless....people only follow leaders. Are you a leader? Do you have the type of personality that people are drawn to and want to follow? Ask yourself these questions and you will find the answer. Good luck!
You should answer more questions so people will know more about you. Also, if your profile is more complete, people can see if your interests are similar to theirs. I try to answer a variety of questions that I have knowledge about, & make sure my answers are informative, interesting, & easy to understand. Without purposely attempting to do so, I have managed to attract over 30 followers (thanks to all of you, I'm very flattered!). Just keep doing your thing on here & it will happen.
