It shouldn’t take me crawling through the mud of social media to find them.
As a heuristic, if it was made for earning money, it's probably safe to close the tab.
Perhaps a community index curated to contain only non commercial websites with no ads or trackers?
The period of time where friction and barriers to entry were high enough to filter out much of the chaff, and the parasites had not yet adapted to exploit everything.
Also I think the internet community itself may be parasitic on other institutions that it is simultaneously destroying. Specifically I'm thinking things like traditional journalism, which is being killed off even though the internet needs it for stuff like Wikipedia.
The modern internet undoubtedly started in the mid-00's. Facebook, YouTube, Twitter, Reddit, all were founded between 2005 and 2007.
The start of the Internet's golden age is a little harder to pin down, but the mid-nineties public release of PHP in '95, or the launch of GeoCities in '94, or the release of CSS in '96 is probably a fair estimate. That gives a good decade of prime World Wide Web.
