@archaeme @ronflaix Basically, GNU social and its predecessor StatusNet, had certain limitations that the original creator of both was unhappy with, so they went back to the drawing board, and made pumpio
Unfortunately, while StatusNet and thus GNU social that it evolved into had for some time not insignificant financial backing, pumpio never got that kind of monetary support, so the project has struggled a lot as said developers try to balance their own primary jobs versus development.
