Really, I do. It is such a great concept, and I hope the developers do really really well with it. (If you haven't gotten your invite to Ravelry yet, then I'm sorry if this sounds like taunting or bragging. Trust me, your patience will be rewarded.)
The only downside (and I admit that the fault lies entirely with me) is that I now have so much less to blog about. I started blogging mainly as a way to keep my projects (current and future) organised, and to help keep my few online knitting friends up-to-date on my progress, without flooding our message board with FO posts. I did slowly become more accustomed to writing about knitting as lifestyle, almost approaching actual journaling levels (which is so bizarre to me, since every diary I've ever owned contains two to three very bland "introductory" entries before my interest waned and it became buried under stacks of "Seventeen" magazine).
So I'm going to give blogging-as-journaling a shot, please bear with me (and I'm going to need to learn how to spell "journaling", since this is 3 times now I've written it with two ls. Thank you little red line...)
I'll be back...
