Developer Jamie Perkins was always curious about new people he ran across on Twitter and wanted a way to look them up, understand what type of person they are and what type of stuff they Tweet about.
With his new tool, Crowd Bio, you can tag people on Twitter. Tags describe a person and what they Tweet about. Tags grow when more people use the same tag on a person, so it's easy to see when people agree on categorization. You can also search tags to find Tweeps tagged with what you're looking for. Cool idea. Check it out.
