I made a diagram yesterday that contrasts #ActivityPub and #SolidProject that is I think interesting to consider.
In the past I've been very active on the Solid forum, and tried to get a collab going with #SocialHub community. A number of points that existed then, are still issues today I think.
Like, though anyone could participate in the standards process via chat, the Solid team and Inrupt were not really interested in their community, hardly giving attention while people were building interesting stuff there.
Also at the time basically all available code was Javascript, making Solid uninteresting or hard to access for other language devs.
But I think biggest issue was that Solid didn't know what it was. It was positioned as 'personal data vault' on the landing page then (but not using this term), but was 'secretly' TBL's desire to reboot the #SemanticWeb. The new web would be all 'Solid apps'. But the adoption strategy for that didn't exist.
