If you want the old internet vibe the dark Web is the place to be. Tor, freenet, i2p.
I'm quite partial to freenet because it's completely segregated from the regular internet and refreshes as the speed of dial up. No interactive web2.0 here.
I'm sure there are weirdos in the web3 spaces, but I feel like they're very outnumbered. Projects like ENS or IPFS are probably much more interesting to weirdos than most "crypto stuff". I2P too, though I don't think this twenty-year-old project should be lumped in with "web3".
I think the Fediverse is a better place to go. Lots of little communities, almost all of run by regular nerds, each one with their own quirks and petty personal drama and constant UI tweaking? It's like forums all over again, except it's now safe to use one password for everything.
Fixed that for you.
