Not to side track the conversation, but before you submit things from the 4E DMG Wyatt copied from the earlier Dungeon Mastering for Dummies (written by Baker and Slavicsek for D&D v.3.5), I'd give priority to things Wyatt specifically wrote for 4E.Sure, that particular interpretation of one quote is far more relevant than the advice, in the DMG, written by James Wyatt, about the core modes of D&D being exploration, conversation and encounters.
Wilderness exploration itself is delegated to a sample skill challenge (based on Endurance and Nature), half a page in the 4E DMG. Contrast the pages upon pages in the 3.x DMG on the diverse natural environments and hazards. That's why the Dummies advice copied into the 4E DMG comes across as a bit different.
Mind you, I'm personally very happy with 4E's way of giving 99% of all mechanical support to combat, and handwaive the rest. Freeform roleplay interlaced with occasional skill checks is all I ever needed for that. I only wish ritual magic was a bit more worked out to aid the non-combat parts of the game, but that's about it.
