Clap your hands, say Yelp?

So, there's this particular site that I started visiting not too long ago. Ever since moving I've been looking up directories to find out what's near me, and along came Yelp. It's an interesting site because it sort of combines the whole review thing with a more accessible map and chat channels. I'm curious to see how it is going to turn out, whether they can truly handle its rapidly increasing volume, and how they can keep the quality in the reviews up---as in keeping stupid or malicious comments out. I guess that's the challenge with any public commentary website. Anyways check it out! (And, no, I wasn't forced to write this; I just think of it as another good resource to know.)
