Tweegee is one of the TechCrunch 50 companies. Kelsey interviewed CEO Shay Bloch on Monday. Here's what Josh Lowensohn of CNET wrote about the new start-up:Tweegee is a virtual world that mixes e-mail, personal organization, and Flash gaming. It centers on an anime-like avatar that users build part by part. Likewise they can use a similar building tool to make their own hosted site that comes ready-made with templates based on what the kids are interested in.
