This is primarily for my mother, to make her get her stuff together and join this, and I warn you: it will hold little to no interest for non-knitters. You know who you are.
From the beginning, I have been very sceptical of the whole web 2.0 experience. I have shunned Facebook, skirted around Twitter (except the occasional stalking moments now and again), never joined Bebo, Orkut or Hi5 and generally felt very good about staying as far from social networking sites as I could. But, perhaps to compensate, I have been steadily drawn to what I see as similar concepts that have a clear focus: Flickr (for photos), LastFM (for music), LibraryThing (for books), and finally Ravelry (for knitting).
