In case you were looking for the link to that restaurant review site in the sidebar, I deleted it.  Apparently, there are some allegations that Yelp is "extorting" advertisments from local restaurants in return for positive reviews on their site.

...six people told this newspaper that Yelp sales representatives promised to move or remove negative reviews if their business would advertise. In another six instances, positive reviews disappeared — or negative ones appeared — after owners declined to advertise.

You can read more about it on the East Bay Express, but until this matter is cleared up, I'll not send any readers to a possibly dishonest site.
