In short, I don't think it has much bearing on our practice. Former GR hosts on the discussion board can learn why; I'm not interested in airing this publicly. In the meantime, I look forward to watching Carnival of the Colonoscopists and every other niche group try to manipulate Instapundit into greater traffic -- if that's not a zero-sum game, it's asymptotically approaching it.
