I've joined a site for knitters and crocheters called Ravelry.
It's really a neat site. It combines social networking with other knitters and crocheters, and allows you to share projects, patterns, pictures, yarn, forums, etc. It even has a "library" to catalog all your books and patterns.
I know this is all terribly boring to those of you who don't knit or crochet, but if you're on Ravelry - add me as a friend, I'd love to see what you're working on!
