Looking thru my LJ "friends" list, I note that there was a significant exodus from the site back in 2012. Most of the people on my list had stopped regular posting long before that. Zannah and SjonSvenson and Ivy_Rat still post almost daily (altho' Zannah's posts are via a feed from VoxMachina). LilRonGal continues to post regularly. So not everybody is gone. I have forgotten how to add LJ user links to the names.
