#solid

are people on here that have opinions about #Solid (the pod technology not the javascript framework / library) why is it good / not good? is it usable? is it in use? it doesn't seem to have the same popularity as i.e. #ActivityPub / the #Fediverse, even though the concept of solid pods seems to synergize quite well with the idea of a decentralized web, as far as i can tell
