I personally thought it was the best article about Y Combinator that covered everything from start to finish of the ones posted here before. I think the bootcamp analogy refers to how fast everything happens over a period of a couple of months when you first join the military, after which it is usually less hectic. That's a good way of explaining Y Combinator to MSN readers, even if startups continue to have hectic lives for a longer time than that, while somebody could go to an officer school for 13 weeks and then go straight to being responsible for 20-200 adults much older than they are, while startups are still trying to get going. Other than that, I think the article explained very well that most people came up with their own ideas.
