I think that fully integrating #ActivityPub into Flipboard's backend is going to be one of the best things we've done since we started the company.
There are three phases:
Phase 1 (Today): Federate 25 accounts to test and learn
Phase 2 (January): Enable anyone in the Fediverse to engage with any public curator on Flipboard
Phase 3 (April): Enable anyone on Flipboard to follow and engage with any public account in the #Fediverse
