Newgrounds would be awesome in the Fediverse tbh, would bring so much content (beyond politics and news).
Image hosting seems to be super problematic with activity pub, especially with something pf Newgrounds' size. I'm super invested in this, can't wait to see where it'll go.
It's just like Peertube. Cool concept in theory, but breaks down once you consider the less fun parts of it (storage volume).
Gonna be really hard to figure out how to make solid Fedi alternatives to image/video-based social media.
