It's common for Twitter regulars to get a stream of new followers, but it's not always clear why they should follow back -- how do you summarize a person's post history in a few seconds? Twitter wants to solve this by launching its #FollowMe tool. The service uses Vizify to build a short, HTML5-based highlight clip from a person's followers, photos, tweets and Vine videos. Most of the legwork is automatic; users only have to edit the clip if they want to fine-tune the results, and any tweet with the relevant link will show the animation in-line. The #FollowMe rollout won't guarantee any additional popularity in the Twittersphere, but it should at least make for a stronger sales pitch.
