Posting recently has seemed to hang up, but when I opened another tab and looked at LJ there, the comment or post was in fact there. It just hadn't cleared back in the original.
This afternoon, I've been unable to post comments in response to comments here. It hangs up but good. Somewhat frustrating as I do have things to say. I can't be sure this will post, either, but it's worth a try...if it does, you'll know I'm not ignoring your comments.
