I think this stems from all these social sites competing with each other. I happen to like them all to be different. After all, I use them for different things. When I want to rant or simply post a long, arduous post I use LJ. I use it to read fic, post fic, share fandom pictures and other fandom things. Twitter I use mostly to chat with my friends. Facebook I use to share information, chat a bit, laugh and funny posts, and play games. Tumblr I use to blog or share fandom photos. I don't need LJ to be like those other places. I have those other places already. That's why I don't use Dreamwidth. I have an account at the ready, but I don't use it because I have LJ.
