HNers of the right age have probably been witness to every big startup in the last decade. I would be more interested in hearing what effects the big startups have had each person's own projects.
Basically, it takes away my excuses. A lot of people think "that sort of luck doesn't happen to people like me", and so they don't even try. But I've met a bunch of people that it has happened to, and they're smart and they're dedicated, but they aren't fundamentally all that different from me.
