One thing that was easier to find on the #web 20 to 25 years ago through search engines is diverse #torrent collections.
I miss those sites were people offered their personal book collections or fan video and image collections of whatever. The type of #site you'd go to to find Richard Linklater's first film or some short film that was shown on some Polish #film festival once but never officially released on any medium instead of what's hot from Hollywood. Sites where people would upload new punk rock albums and skateboard videos every day. Places were you would find TV recordings of all sorts of stuff from people who just couldn't accept that this stuff wasn't archived publicly.
Knowing about the deep web I'm sure communities like this are still around. But I don't even know how to find what's been shown in #Cannes this year.
