As far as I can tell, RPGPundit's blog really is the most popular (Uruguayan) gaming blog on Earth. I don't always agree with what the Pundit says and he's more strident in tone than I usually like, but he's got the most interesting gameblog I've yet to encounter. He's worth a read whether you love or hate his ongoing war with the "swine" in the roleplaying hobby.
"Man, is there anything Jeff CAN'T do when it comes to gaming? This guy is like a critical 20 every roll. Jeff can bite the heads offa five game geeks, including their sorry-ass DM, and spit 'em into a large duffel bag ONE AT A TIME!...that's just the kind of messed up bastard he is! You think yer a gamer, punk? Well..do ya? Jeff will depants your weasel-ass right in front of your grandma."
