It's interesting, when Hacker News first started (and was called "Startup News"), I used to make ra-ra comments like this all the time. Like the author, I had little practical experience in actually succeeding at entrepreneurship. And yet they'd be voted up
really high. Once in a while, some old salt like, say, the guy who founded Digg or the guy who founded Symbolics would reply and say "You're naive and ignorant. You won't think so poorly of jobs once you've run your own company for a while" (in nicer terms, of course). But by and large, Startup News loved wild-eyed optimism.
Now, the vast majority of comments hold that same sort of "Well, it's more complicated than that, and I'm quite happy with my 9-5" view. Sometimes even my own.
I wonder if that's representative of the economy changing, or if it's representative of the site's audience changing. If it's the former, maybe it means that now is a good time to found a startup.
