I've heard ActivityPub described as two-way RSS. If so, there are imho more direct ways to arrive at that. I think it's possible to create a federation system that takes a few days to implement. Maybe it doesn't need all the features they've put into ActivityPub. I'm pretty sure a lightweight social network is what's called for now. I know 20 different ventures have started up to do this, but isn't it weird that none of them have built on RSS. That's the only approach imho that has a chance of doing something unique here. I'd rather work with other people, but I'm not into replacing simplicity with something that's not very simple.#
