This post by "rightroots" mastermind Patrick Ruffini might strike you as a little obscure, but it has important implications: what if we're sharply overcounting visitors to high-traffic blogs? Advertisers are using far more sophisticated metrics, to be sure, but these Sitemeter stats have some weight when it comes to projecting an appearance of real-time political influence. I'd be eager to know more. Then, of course, there is a wealth of opportunities to "juke the stats."
