I updated my first post on this topic with a few words, updated from last January. A year later, the Wiki's gotten pretty viable. Still incomplete in various areas, but we're at least better off. :)
More importantly, though, I want to get this through people's heads: Stop linking to the Wiki's front page with a snyde "look it up" remark. Start linking directly to relevant pages. I cannot stress this enough, and I can't say how much the former pisses me off. Honestly, does it help? I wouldn't expect a new person to just know to look up such technical terms "Console" or "Character WAD". Just bend a little bit, because that does help more in the long run.
