I signed up for the Tea Party Nation site to see what was going on there. No wonder that thing is not open to the public. All kinds of paranoid ramblings, along with some of the most illiterate and ignorant posts I've ever seen. The URL is here: http://www.teapartynation.com.
To check it out, use a throwaway email account to sign up with. Then sit back and chuckle at what you see. Or cry.
