I’m futzing around with ljcrosspost (original), a new plugin that automates crossposting between MT and LiveJournal. If it wipes out all my LJ posts, I will be very sad.
… OK, it’s a nice plugin but it doesn’t really make it easy to customize the post title and it doesn’t provide easy access to the permalink — so I can’t easily create links back to the blog side of things. Maybe in a couple of revs. It’s a damned cool idea, though.
