There certainly are active communities still on both LJ and DW, just seems that a lot of individuals that used to brighten my flist have moved on. I filter out communities from my flist so it tends to be quiet.

Like you, I don't have and don't want FB and can't really deal with Tumblr's format for the kind of interaction I want. I have Twitter that I use occasionally when I remember.

Yay, hopefully various kinds of posts will pop up over the next few weeks :)
