Looks like it has some growing pains. Most of the links at the top jsut link back to the main page. Alot of people have the "Tumbleweed" badge - "Asked a questions with no answers, no comments, and low views for a week".
It's an interesting idea but I'm not sure how many lawyers who normally charge hundreds of dollars an hour to answer stuff like this will really decide they want to do it for free. I'd like to see it take off but I think it may have a tough time.
