MySpace deserves special mention. (Any web programmers reading this?) Have you looked at the source for those pages? It's a nightmare! It's like Tom's accidentally successful garage project. The ability to create a theme looks to be not by design, but rather only possible because browsers are really tolerant towards erroneous usage of CSS. The most impressive aspect of MySpace is that News Corp paid so much for it.
Also note the new links for my sub-pages. I expect I'll be steadily adding more to that as time goes on.
