BlastFollow enables you to follow Twitter users who share your interests en masse. This web site is a production of Triangle Information Solutions. To use BlastFollow, simply enter a favorite hashtag (for example, “americanidol”) in the box below. Then, click the “Get Users!” button. After a few seconds, you will see the number of users who tweeted with that hashtag recently. Then, you need only enter your Twitter name and password and click “Blast!” You will start following all of those users. You can usually see the progress on a user-by-user basis.
