Wikipedia itself has descended into the same pathologies you see in 'science' today: a bunch of gatekeepers who, by account of having been there the longest, have set up a moat of rules and 'culture' and such, to the point where newcomers are shut down or drowned out. I'm not saying it's impossible to get in; but only those that sufficiently mould themselves to the existing people and structures will last long enough to become fully accepted. And so the system sustains itself.
