One of the paradoxes that makes the internet such a suggestive place is that, on the one hand, we perceive it as perpetually in motion and changing, and, on the other hand, it has this god-like immortality to it: It seems like it won't die and is not subject to decay, and that everything can be unwound, unlike present-tense experience, where you can't archive the present moment, you can't go back and read it over again. That's the fundamental hallmark of the internet.
