I thought it was worth trying, in case anyone had remembered it existed :-) At least it's somewhere people can come and say, 'Hi, I'm alive, I just can't post to LJ', which is what I've been trying to do for days without success.
I use my IJ to rant about LJ, mostly. And I kept up my daily writing posts there.
Perhaps you should put a sticky post here on the IJ comm, saying that if LJ falls over we can camp here temporarily while LJ sorts things out. And it'd at least take a small amount of load off their servers if we weren't all trying to get through to Denial at LJ when there's an attack.
