If you’re not happy with how communities are ran you can create your own. Nobody is hogging precious namespace so you can spin up @numismatics@treants.penis and run it any way you like.

It does federate for sure but implementation looks quirky.

If you’re a publisher only then RSS/Atom makes much more sense, especially if you want to retain ownership and control over content you created. If control is not important to you and you want to incorporate social aspect into your website (comments, reactions) then ActivityPub seems like a convenient way to go about it.

One thing that I strongly disagree with author of the blog post is the discoverability aspect. Yes, initial federation kind of sucks but at the same time your readers on Mastodon will be able to boost it and increase your reach.

Reddit is astroturfed to hell, I prefer my posts to come from humans rather than companies trying to game system for financial benefit.
