I've seen Quora referenced a bunch lately, and have been excited to try it out. The design (from the outside) looks really good, and I suspect that your team has crafted a really polished UX. I'd love to check it out. But ...

I'm not going to sign up via Facebook Connect, but it's not because I don't like linking that profile. It's because the Facebook ID approval page notes that you'd be publishing content to my wall.

Just another datapoint.
