cozy 90s BBS forums, obscure blogs, etc.
All of them, if you browse with Links.
I get most of the stills for my Star Trek memes from trekcore.com which has a pretty old-web feel to it.
I haven’t visited in a long time – but I can’t imagine Craigslist has changed much.
It has not, though there really isn’t much posted there anymore. Facebook marketplace has replaced it for most stuff. :(
What about craigslist casual encounters? I’d love to see facebook’s attempt at that.
Not a website, but since you mention BBSes…one thing that would look pretty familiar to a 1990s Internet user would be most of the text-based MUDs, the ancestor of MMORPGs, that are around.
The MUD Connector is still around, and still has a list of active MUDs.
While I suspect that most dedicated MUDders use dedicated clients, the base protocol is still normally telnet, and you can use a plain old telnet client to play…a protocol that predates Internet Protocol itself.
