Via the excellent You're It! blog on tagging comes word of Dinnerbuzz, a folksonomy for restaurants. Since it's still nascent it hasn't quite reached that critical mass of useful amounts of data yet, but the concept makes sense in the same way that 43places does: everybody travels (or, exists somewhere), and everybody eats. It would be fantastic to be able to go to Dinnerbuzz and be assured of finding a great place to chow down while travelling in unfamiliar territory, or to discover unknown places closer to home. As Alexandra Samuel notes in her post, it's a glaring omission to not be able to narrow a search by rating — so that you can limit your results to only the top-rated restuarants in Palo Alto, e.g. It also remains to be seen if the site will attract enough of a userbase to invoke whatever strange alchemy can transmogrify a codebase into a community.

Update: Justin Smith tells us search by rating has now been implemented! Now that's my kind of turnaround time. ;)
