@mordremoth Seconding several of the other responses, there were genuinely interesting routes through the web courtesy of web rings and directories, not to mention pointers from usenet groups.
There was something appealing about the chain-linked hypertext flow of web rings, albeit that (and I was very young, so my memory is hazy and probably misinformed) there must have been a substantial element of gatekeeping involved in the membership of those rings. I guess that, by nature, is one of the ways in which 'hand-vetting' works, and it is no more curated (and possibly rather more coherently curated) than a search engine built on unknown and largely inscrutable algorithmic processes.
And, do I miss that long-lost constellatory phase of the internet? Absolutely.
