In a quick post, allow me to promote Ravelry.  Similar, in many ways, to social networking sites such as Facebook or MySpace, Ravelry proves to be a lot more interesting, and a lot more interest-focused.  You can search for patterns, people, designers, books.  You can see finished projects, UFOs, and join groups of knitters with similar interests.
You can find me on there as JavaStix (of course) and I love to hear about projects and yarn. 5 sheep.  All the way.
