I spent a little time on TGP, but tbh it was only to read about Vertex and a P&W guitar builder who turned out to be another scammer, I haven't been back since.
There's a UK guitar forum I spend some time on and a Sci-Fi & Fantasy forum that I visit from time to time, the second of those being the nicest forum I've ever spent time on.
I have a "friends only" approach to FB so that makes four places where I may be found regularly posting. I also browse Imgur but rarely comment and have never posted anything so far.
There was a time where arguing with people was entertaining now and again, but these days I prefer peaceful, mutually supportive places and include ILF in that
