Xanga: Worth a page! There's a LiveJournal page, and Xanga.com is a very popular alternative. I suppose blogger/blogspot is too, not sure if they have a page. Actually Orkut too, there's a large UCD community there from where many people first heard of the Daviswiki.
There is nothing more frustrating while waiting in a computer lab line then watching people (specifically those of the female origin {from my observations}) idly check xanga after xanga.
