There are more people camping than ever. And many Internet forums (RV and otherwise) are alive and well. I personally really hate Facebook groups. It's a clunky platform for these sorts of discussions.
Here's my view. Some years back when this forum was really busy, there were a lot of people that just caused a lot of issues. Name calling and backbiting were common. Even the least controversial of subjects frequently went off the rails. Lots of good people got discouraged and left, myself included. Then the moderators tried to clean it up. Then some moderators got heavy handed. More people stopped posting. This is what is left. We seem to have a good bunch of hard working moderators now, and very civil useful threads, but few people left to participate.
