Anon User has been steadily decreasing in prominence on Quora.

I signed up in March 2010, and Quora has been my favorite site since then, mainly due to the initial population of users, those users setting a high standard, and then new users carrying though.

There are a lot of Quora users I actually trust more than my facebook friends, and several I also like more.

The slickest realtime UI I've seen to date makes the whole thing even more pleasant.
