Attitudes like Jim's don't just discourage us from being active on FR; it caused me to leave the GOP altogether. I've recruited quite a few others since then, because of the same attitude.
That said, this is Jim's site, and he can cultivate whatever culture he wants. And I may not be active anymore, but I do still read the breaking news section in my RSS reader. I think the fact that I still read speaks volumes about the value this site has.
