I really love the usability of this, I love the form fields and the javascript usage to make all the subtle changes (eg, your location changes the currency) -- its great.
I also love the large form labels "1" "2" "3" telling the user what to do - very nice touch.
I think the toughest part will be getting eyeballs - you need jobs to get users to get them to add their job positions.
I'll blog/twitter about it - are you on twitter?
