Hive just shut down their entire app: https://twitter.com/TheHIVE_Social/status/159811907190799155...
NB, I don't use Hive and have no interest, I moved to Mastodon because I want to be in control of my data moving forward.
I wonder if I'll be able to determine the real Hive of Twitter if things switch.
If that (Mastodon or other implementations) are not good enough, make your own or get involved with the W3C to standardize AP v2.
