Another thing people find surprising:

Self-hosted Reddit servers used to be commonplace.

Now imagine if ActivityPub existed when Reddit was open source.

Well, we don't have to imagine it. There's Lemmy.

But my point is that every self-hosted Reddit install could have been federated if ActivityPub existed back then.

Of course, even if Reddit was still open source and supported ActivityPub, I'd probably prefer Lemmy since they use an AGPL license.
@atomicpoet Do you also like microblog.pub? I believe it is modular and easy to manage.
@house I haven't tried it.
