Are you on Twitter? It's a more common platform for political stuff. Facebook is for friends, and unless you want to discuss politics with all of your friends at once, why not just keep it to personal stuff?
And character limits.
All the obvious "blue check-mark" people have zero insight at best. There is a whole weird world of small follower count people on there. Small communities. People with unique ideas. People that will actually respond to replies.
Again, I don't think it an addiction you should necessarily cultivate, but there is value to be had.
