Not to disparage spaces like NeoCities, but to quote the great American singer/songwriter David Berman:
Punk rock died when the first kid said
"Punk's not dead, punk's not dead"
That is - these spaces will never quite be the same as what we once had, because they're fundamentally nostalgic. The "wild" internet was also once the vanguard, the future, and that excitement won't be recaptured by going back.
