Dw steals people and makes them "Dw-centric"; In common with other things that sprout out of something else and try to borrow its success, there is a certain amount of the Emperor's New Clothes at work here. I quote the great and wonderful

Also, I am going to make a post soon about why you should not fear the fandom's disappearance from LJ. Because seriously, if you are afraid that people getting Dreamwidth accounts means that fandom is fracturing, you may not quite understand how this all is going to work.
Short version:
1. Dreamwidth has built-in crossposting to LiveJournal, so there's no reason you can't post to both places if you're on Dreamwidth, which means all your friends who went to Dreamwidth? 99% of them will stay on LJ too. LJ, like IJ, is useful as a mirror.
2. Dreamwidth allows you to friend LiveJournals, so you don't need two flists if you're on Dreamwidth OR to worry that people aren't reading your LJ entries if they're on Dreamwidth.
Seriously, guys, the gnashing of teeth is very distracting. And bad for your molars, too!
