Why have those website layouts that involved image mapping a ton of little PNG files that were each about 55kb and there's probably about twenty of them, making it about four minutes for a site to load at best, and they all showed up one at a time, so you'd get to say 'oh, there's this guy's head! and his shoulders! what the crap, why are his feet there? oh, there's the torso'
I mean, this is the sort of time that they'd actually almost be practical. Back a couple of years ago when they were big, I know I was still on dialup.
What web fads have you noticed missing lately?
