Well it appears that I managed to migrage from livejournal to wordpress with my posts & comments intact. LJ’s export feature sucks (no comments, only 1 month at a time), but I followed these fine instructions from Voices from Catland (!!):

Mad props to them, LJarchive, and WordPress for making the export/import so easy. Otherwise I probably would not have done this at all. I had to touch windows, but otherwise it was painless.
