Ok, I've only been on Ravelry for two days (id: sancocho) and I've already added my projects, yarn stash, future projects. I worked up the courage to add some friends today, mostly folks whose blogs I frequent. My goal is to add all my favorite knitting bloggers. Ultimately I think Ravelry is going to be a great place to learn about complex knitting techniques and fibers, especially handspun/dyed fibers. I haven't taken a huge plunge in that direction yet but as my projects get more complex I think using unique fibers will be ideal.
For everyone who is still on the waiting list it won't be long and it's very much worth the wait! Hang in there.
