Earlier this month, I asked about archiving my LJ. britgeekgrrl suggested http://fawx.com/ljArchive/. There seemed to be a flurry of people that were interested in this link, so I thought I would post it so everyone that read the first post will get a chance at the recommendation.
devonapple also pointed out LJs tool for exporting your Journal:

I haven’t tried either, so I have no recommendation. I plan on giving the first one a try.
