Tweet Annotations
Link: Tweet Annotations
Annotations promised to upgrade tweets from being a 140-character postcard to being a 140-character message written on the outside of an envelope. What was inside the envelope? Whatever a developer could imagine.I remember that I was really excited about the tweet Annotations announcement at Chirp.
Seems like Twitter has reversed course since then, and today all of the metadata attachements in tweets are handled as URLs in a tweet, such as photos, videos or even quoted tweets. The API seems to attach a little bit more metadata (like quoted tweet ID), but the current design was to work with old clients gracefully.
If annotations API were implemented earlier and correctly, all of these media attachements could have been handled that way.
