I have newer heard about web cliques until they were mentioned today in wired, but I seems like a new web phenomena, which binds servers and people together in communities based on interests so they can discuss, chat and show off their interests. If you have a thing with some kind of food, chocolate or if you think you are an http://members.aol.com/swankivy2/joincliq.html#ucsuper, there is a clique for you. It is interesting how this will evolve, but if this is connected with weblog's then it should be easy to build a kind of communities on top, based on systems like drupal.
