Great work! I have one suggestion though. Let users immediately start filling in information and THEN let them create an account. I wanted to try it out, but then realized I needed to put my email in and select a password. Not a bad thing, but you'll get a lower bounce rate if you save the account creation for later.

(Also, this sort of thing would work great with Facebook connect -- you could pull name, education, work history, and phone numbers automatically. Maybe LinkedIn has an API to?)
