Are there people here considered to be on the fringe?
Probably.
Old? Young? Highly educated? Hardknockers?
Yup, yup, yup and yup
Ultra conservative? Moderately conservative? Libertarian? A few self confessed Democrats?
Yup, yup, yup and yup
Name your element, it's here.
IMO, Hannity is jealous of the popularity of this site, and in his mind, a competitor. Rather than providing a better product (he can't), he's trying to demean FR in an attempt to bring business his way.
Agreed. Sean is a day late on the blogosphere and is probably jealous of FR's success in taking out Rather (with the subsequent help of actual blogs) and otherwise. Sean's got a bit of an ego problem...
