Because we're going to get such a peek behind the curtain with the planning videos, campaign diaries, and Matt's frequent explanations and discussions on Twitter and Reddit, I feel like Matt's show is going to be quite different from the usual type of show. We will probably therefore need a different type of wiki to document it.
A big part of the value of Matt's work and the reason why he does it is for the benefit of DMs. I would like to emulate that spirit by being up front in situations like with the Teeth of the Dragon, when Matt has said that he simply hasn't made up the facts in question. We shouldn't pretend, in a lore-y fasion, like those facts exist but are vague or unknown, if we can document that Matt simply has no idea yet how it will work.
When the Campaign Diaries and Campaign Planning videos are out, we'll have a lot more of that type of content. I would like the wiki to document the content of those videos as well as simply the lore and background of the characters. If Matt says in the Campaign Diary that he completely changed his intention for a character because of something the players did, for example, I'd like to have a place to document that on the character's page.
I'm not sure at all how this should play out in practice though, so I'm eager to hear other people's ideas and opinions.
