@atomicpoet Given that I worked in the Drupal camp for years, I'm watching what's happening with them and ActivityPub with a lot of curiosity.
Given that historically, Drupal dev tends to be heavily driven and financed by client need, and a lot of those clients have tended to be on the more corporate end of things.... I suspect we'll see a boom of development there when people start imagining the uses of ActivityPub that go beyond microblogging.
Or at least, that's my prediction.
