Yeah 4chan sucks but back in highschool/college I used to browse /mu/ a lot and download music recs and make those collages with favorite albums, etc. It was a very chill vibe, and while I wasn't very political at all back then (read: lib) I always got the impression it was just a bunch of music nerds thumbing through threads looking for cool and obscure stuff. Lots of memes about ITAOTS and MBDTF etc.
I just found chapo.chat but I'm wondering if anyone else here lurked on that board?
4chan in the late 00's/early 10's, when every second link on there was a screamer was good, but then Atomwaffen found out about it.
