Startup on socializing with TV show casts desperately needs feedback

We just built this site a month ago

http://www.tivify.com/

It's not a full-time project as you can see. BUT we want to kick it around to see if anyone sees any usefulness coming out of it OR if it can be turned into a different idea.

In a nutshell, we collected all celebrities and TV show casts Twitter feeds and put them in one place, organized by the show they were a part of. Based on your favorite show, you can see which cast is tweeting recently.
