Lots of sites offload payment directly to stripe, PayPal, etc. many even let you choose the provider. I don’t see why it wouldn’t work the same way.

Wordpress has an ActivityPub plugin to federate your content with Mastodon, Pixelfed, Misskey, and others, and will push their comments back to you.

I think he’s pragmatic in the “whatever tool gets the job done” sense, but not in the “this is the job we should be doing” sense — if that makes any sense :)

This series of articles and replies has really made me think about the structure of the Fediverse (as a casual user, though in the software biz), and for that I am very thankful. It makes me think, though, that just as open source developers got around the “free as in speech vs. free as in beer” issue by using the word libre, if the Fediverse needs another term – or even just call it “capital-F federation” – to distinguish the kind of first-class federation that Christine and ActivityPub represent vs. the definition that ATProto has suggested (and even vs what lots of regular software/service companies mean when they describe a system of microservices as federated).

ActivityPub is not a great fit for realtime chat. As others have noted, the Matrix and XMPP protocols are federated and designed for exactly this use case.
