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 collect RPG and tabletop wargame books that are interesting to me or as archives of old versions of whatever game. A lot of this stuff has been out of print for decades and so I download it when I see it. If I really enjoy something, I might track down a copy. But no way in hell am I paying $2~300 for some second edition rulebook of whatever game just because it hasn't been available since 1983 or whatever the fuck.
