I tried to make it clear in the piece that I think Startup Weekends are a really good and useful event. I think that everyone who participates in one, no matter what experience they have had to date, will learn something from one. I definitely did.
My complaint is more that our "startup society" pushes us far more toward the Startup Weekends of the world, and away from "boring" jobs at large organizations--and that's really silly, since (as I argue) a great case can be made that the most viable, most fund-able startup ideas will come from working at large organizations (mo' money, mo' problems, mo' moving-the-needle-a-little-means-big-returns).
