Wired News: Web Cliques Too Cool for School:

“A clique has several mandatory structural elements, which include About, Rules, Members and Codes sections. In general, a clique will clearly define its topic. Its rules section lays out the governing principles of the page, and its membership section lists links to many on-topic sites. In the codes section, small graphical or text-based buttons that link back to the original clique are presented for all member sites to post on their pages.”
