Is your institution a W3C member? Do you like decentralised social networks? You probably do since you're reading this on Mastodon. Ask your AC rep to vote on ActivityPub today! (or, before the 16th of Jan). If your instance is up to date, you're probably using this standard right now. It would be a shame if it didn't become an official W3C Recommendation.
