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?
Yes. As they say it’s a disease. Though in my case it’s mostly limited to media. Movies, TV shows, take up the bulk of space and to be honest I spend more time on curation and tweaking than actually hoarding new stuff as I am a little picky and don’t just grab anything.
