When I first started using usenet in the early 90s, I spent days going through the entire list of newsgroups my provider had. IIRC it was somewhere around 6000 groups at the time. Found all sorts of interesting things that way. To your point, that's not exactly a scalable solution and not one that most people would do :) I'd counter that though with the aspect of one stop shopping, which e.g. Reddit also has. One thing that kept me on Usenet far longer than most was that with one app (my newsreader) I could access limitless topic specific forums. Instead of having to go to a bunch of different sites, each with their own logins & quirks, etc. To this day I still prefer applications like that, for instance it is something I really appreciated about Twitter until recent changes.
