What exactly WAS the "old" internet anyway?
100 half-baked sites hosted on Geocities, Yahoo, about pointless stuff, covered with gif-vomit that looked like epilepsy simulators?
Serious question: What do the rose-tinted glass wearers actually think was of objective substance on the old internet that's nowhere to be found now?
You can find random pointless stuff now too, just that except Geocities/Yahoo it's Intsagram/TikTok/Twitter etc.
If you mean self-hosted websites, they're still here.
If you loved all the Flash toons on Newgrounds etc there's unironically a lot more shorts and animations on YouTube now, if you but search for them (I suggest Weebl, David Firth, Sechi, to start with, and let the algorithm soak up the weirdness)
