Yup. I actually got a code yesterday and set up an account but haven't started posting or crossposting. I'm going to let things go into the open beta and settle down for a while, see what everyone else does. And I'm trying to think of useful things to do with my IJ account -- thinking about cross-posting my wordpress blog there in the short run (since I do post in that one about twice a week or so), it's mostly a knitting blog but it would be original content.
