After reading through all the answers, I've come to the conclusion that Quora is the most vapid, rockstar oriented community ever. To everyone who claims the HN community is dying, go read quora. It's all about me-too posts (which is evidenced by the fact that this post consists of 40 PG regurgitations and ~5 great answers), where the biggest rockstars get voted up the highest. At least HN still has deep, contextual discussion.
