Try 1 or more of the following:
- You need to have a blue birdie twitter button on your blog that says “follow me” (search google images for follow.png)
- Follow more people, a certain % think it’s “good manners” to follow those who follow you.
- Become more interesting and/or famous and people will think it’s cool to follow you.
- Get totally plugged in to twitter – use it all the time, if you can stand to try to find some purpose for it
