I use it to keep in touch with friends and family. I don’t ‘do’ politics there, so no problems.
It’s a free tool. You don’t have to be. :)
I have used it to reconnect with old skydiving friends and some old friends from my days in the Canal Zone. There are some great threads on Drag Racing and any aircraft you can name-—there is an X-Planes thread for people who like those models, from the Bell X-1 to the X-15 and such.
