I am @humanetech at Mastodon, #FOSS and #Fediverse advocate, mod at SocialHub, and facilitator of Humane Tech Community.
I help fight tech harms and “Promote Solutions that Improve Wellbeing, Freedom and Society”.
There are a couple share project listed on https://delightful.club/delightful-activitypub-development/
That second comment by goplayoutside says it well: “Maybe the modest technical hurdles are a feature, not a bug.”
I think it is a feature, and the same is true for Mastodon and the Fediverse as a whole, imho.
