I just signed up, and the web site is remarkably slick. Anybody who's made web apps knows how hard it is to make something that just does what it's supposed to as well as this. I especially like the easy integration with GMail, Facebook, and so on.

The signup process is a bit long, but I'm not sure if that's a bad thing.

Edit: When I selected "Electrical & Computer Engineering" from the drop-down menu of departments, the ampersand got turned into "&". I'm pretty sure this is a bug.

I disagree. I found the interface clunky and the research interest categories were really sloppy (typos, duplicates, inconsistent granularities, etc...). Also, the inability to click on section names during sign up was very frustrating.

There is an alternative venture http://www.ulurn.com. Not as successful though...
