I'm not a subscriber, so I've haven't read the articles in detail, but there were skills grouped by role and ability score (to make it easier to pick an even spread rather than have the rogue rolling Bluff, Diplomacy and Streetwise while everyone else waits for him to finish), advice about aiding (since, as the article admits, aiding completely wrecks the whole idea), stuff like that. Mostly (very insightful) advice on how to run the game when non-combat challenges are concerned, rather than the new subsystem that seemed to be promised before the books came out.
