surely not challenger? cherynobl? reagan? aids? tear down this wall? cable television?

i did an internet search and there's a lot of stuff about kurt cobain. so generations only happen with frustrated kids of a certain class?

i mean i basically define my own generation as "people who grew up with aids, sexual revolution, post-affirmative action politics, environmentalism, etc as realities and not movements, who understood people were scared of the cold war but don't remember any of the tension personally, and came of age as the internet came of age" but i don't have a precise definition of x other than i'd think you'd have to remember a good chunk of the cold war.
