I have been on LJ for ten years, and it's gone down seriously twice in all that time. (The first time being earlier this year.) I think you're being ridiculous when you complain that they were unprepared in not planning for this situation. It's pretty unusual for LJ to go down to this extent for this period of time, and I can't blame the mods for not expecting it.

That said, I haven't heard of them setting up emergency alternate means of posting yet, which is kind of weird. I've already heard of a couple other challenges/fests coming up that have set up other methods of posting in case LJ doesn't get its act together soon.
