Extratasty is a "Web 2.0" site that lets you search and tag your favorite alcoholic drink recipes. Which means that it's easy to use, has high quality design, and uses "tags" as a form of navigation.

I'm coming to believe that all "web 2.0" really means is graphic design and information architecture that isn't insanely bad. A search on Google for "drink recipes" yields 13.5 million hits, yet I instinctively like the Extratasty site better than anything I've seen before because of its clean design and usability. - Ari Paparo
