Same here, but most of my communities are over on LJ and I haven't found any communities here that are as active (or cross post), so I am stuck with twin accounts on LJ/DW, where I do fandom things on LJ and Journal writing (I do cross post though), and F!S on DW...

I have a Tumblr. I use it, but only for the pretty pictures and so on. I don't exactly know how one can have an conversation on Tumblr...
