The difference with Dreamwidth is they're willing to change and upgrade to make it a better place for fandom. It's not going to be stuck with one thing but able to change with the times. It's not just another journaling service, it's one that is looking to be the best and FOR its users. I don't see a reason to stick around with LJ just because the best new thing hasn't been discovered yet. We have to make the best of what we have because who knows when that new thing, if there ever is, will happen.
