I've been posting to Joe Rogan's messageboard on occasion the last few months. I'm pretty sure it gets more traffic than this site, but I'm not sure. People on there are about 50/50 Ron Paul fans, many "non-fans" like what he has to say on the war but don't like his economic philosophy. I posted the Hayek/Keynes "Fight of the Century" video and had some arguments with some Keynesians a week or two ago.
If you want to venture over there to post, know that you will be exposed to pornographic imagery and probably much more.
Feel free to make friends with myself and ClayTrainor, who is a relatively long time poster over there.
