Agreed! @Hannah and I talked about this in the 5yr podcast, right at the end :)
We have a test MVP locally that we’re toying with for an initial non-activitypub prototype to see if it actually feels useful to connect different sites together. We’ll probably roll that out first in a very minimal way to gauge interest, but the long term idea would definitely be to use activitypub properly.

I don’t see a reason why a self-hosted blogging platform wouldn’t implement it
Because we literally only have 2 full time product developers serving several hundred thousand installs with several million users, and this is but one of several hundred feature requests, and that’s before even taking into consideration any ideas or plans which the team building Ghost actually have themselves.
Try to be a little charitable when thinking about how and why (or why not) things get implemented. It’s almost never an obvious black/white decision :)
That said, Ghost is open source, so whenever people contribute their time and skill to work on the features being requested - there’s a lot more we’re able to do.
