It was a ghost town for a couple of weeks, after the first exodus. Activity has picked back up, but it seems like about half of it is dug up reposts from 1 wk - 10 yrs ago. So, bots? Not sure.
That seems to be the gist of it. I mentioned it in another thread, but new content there is just dismal now. Aside from the top 15-20 posts, everything below that fold hasn't changed in a couple days for me - which used to age out every few hours.
