@cwebberChristine Lemmer-Webber @laurenshof I think one thing we'll have to do in the near term is dual-stack on the API client side. Targeted apps with narrow functionality, like a share button, could support both APIs. It's relatively easy to discover which API(s) a server supports.

I also think adoption of the ActivityPub API will follow a ratchet pattern between servers and clients.

We're already seeing a number of server implementations appear.

This is making clients like https://checkin.swf.pub/ or https://github.com/evanp/ap possible and interesting.

As these clients increase in functionality and popularity, we're going to see pressure by users on more "mainstream" servers like Mastodon to implement the ActivityPub API.
