It's wild to think about how anybody found info back in the day. Forums were probably the big one I guess? There was always something magical about being linked to forum and finding a wealth of info there, and entire domains of knowledge.
FWIW stuff linked from HN & friends is not always the best, but I am pretty agressive about sticking RSS feeds from blogs that get linked here. That gives an inflow of interesting stuff people find. It's not a thing you can do in one go, but after a while you have a lot of neat stuff from people who cared enough to post it.
