I feel like Wikipedia is doing a pretty solid job of holding onto that dream: no shouty content, pure information that's maintained by those who are interested in it, and a fairly well outfitted battalion of bots that fend off adversarial edits
Wikipedia is pretty good for its specific purpose but it’s far from the promise of the open web. Wikipedia has a number of authoritarian moderators who will revert people’s changes for opaque and arbitrary reasons.
Maybe if you took all wikis as a collective then you could get something a bit closer. There’s still the matter of finding them so it’s not ideal. Then there’s the matter of ads. Wikipedia doesn’t have them but other wikis are rife with them.
