I really used to enjoy /r/datahoarders. Except for how right wing it was. Too much focused around the interests of white, male, anglo, north american, cis, het, rich, etc etc. Libertarian. Occasionally in the best way, more commonly in the worst ways.
Is there any such communities which are more expansive than archiving every Nirvana bootleg or getting the most hi quality version of The Simpsons? Or any interest in such a thing?
I'm not as intense as any of them but I'm pretty proud of my media collection, especially the niche stuff. A lot of lesbian cinema, and though I haven't watched most of it, I've got a decent collection of soviet cinema too.
