I'm late to the party, but several people on my friendslist have reported that LJ is in trouble. I think it's not a bad idea to back up my LJ blog anyway, regardless of whether or not the company running LJ is about to go belly up.

I use a Mac. I do not want to save my blog as a PDF.

Help?

(I could probably also do this on my office computer, which is a PC...though downloading software might be tricksy and I'd need to save it to a CD or memory stick. How big is the file likely to be?)
