I think I agree. If you decide not to get a real job while searching for startup footing, make sure that you're learning enough to balance the opportunity cost of salary, on the job learning, and startup stuff on the side.
What you don't want to do is end up like Seth Rogen in Knocked Up -- unless your goal is to be a stoned slacker. Note that Katherine Heigl is unlikely to sleep with you in real life.
Mixing the job suggestion (which is probably good) with the idea suggestion (something people are biased against: execution vs ideas). alaskamiller's comment below/above is more practical in terms of the job.
