Dreamwidth is an alternate blogging site, made mostly using a lot of the original set-up and ideas from LJ. It started up... I can't remember how long ago, when some folks were unhappy with some of how LJ was handling some aspects of business (those who know more than me can comment in more detail).

There have been some hefty denial-of-service attacks on LJ this week, and in response a lot of my friends have decided to either abandon LJ and move to Dreamwidth, or at least reserve a seat over there and start keeping an emergency bag packed just in case.
