BlastFollow enables you to follow Twitter users who share your interests en masse. This is accomplished by searching for users who have tweeted with a particular hashtag recently. For example, if you are interested in ISTE 2010 conference, you may want to search for users whose tweets have included the hashtag "#ISTE10". This would be useful if you are using Twitter in your classroom for students to follow a particular class thread.
"We've examined over a thousand candidates, looking at their tweets, followers, interaction with users, the length their account has been active, the quality of the sites they link to, and even the general appeal of their tweets. And, after careful consideration we have compiled this list of the Top 50 Educators on Twitter who have made strides not only in social media, but in the classroom as well. The tweets from these educators are encouraging and provide a wide swath of resources that can help you accomplish your education resolutions this year."
