For card pages, I'm taking my cues from Hermit and Urchin. The article goes on Hermit's page, even though it also discusses Madman as well. Madman has a separate page with FAQ and secret history and whatnot, but strategy tells you to look at the Hermit page. For the Travellers, I think having bits of strategic quips on each separate page is fine, but certainly a full-length strategy article should be on the Page page. For Split piles (other than Castles, which handily has an excuse to have a separate page), I think the full article should definitely go on the top card's page. However, I'm not sure where the randomizer art should go, though I think having a separate Catapult/Rocks page would just be silly, awkward.
