Buzzfeed already does that, though I presume that their objective is to damage control as quickly as possible if an article generates a lot of negative responses rather than cause chaos. See https://en.wikipedia.org/wiki/Wikipedia:Identifying_reliable_sources/Perennial_sources#Sources https://en.wikipedia.org/wiki/Wikipedia:Identifying_reliable... > BuzzFeed may use A/B testing for new articles, which may cause article content to change This is actually one of the reasons that make things like git repos (given a certain commit hash), torrents, and ipfs (except IPNS/MFS) extremely attractive - nobody will be able to silently change things afterwards.
