Hrmm, it seems that the not-maintained-since-2006 livejournal client I used to use doesn't work with Dreamwidth.
I've asked on a couple of communities what, if anything, has changed. I'm seeing this list claims that it works, but at the same time, on searching for "Dreamwidth Flat Interface" I'm seeing vague mumblings about the interface being deprecated.
Hopefully someone can help me out.
In the mean time, I'm just posting via web form, which is so blasé.
