No matter how disciplined Spolsky was with the funds, nothing's ever the same if you know that you have the option to just inject a bunch of money into one of your projects should the need arise (and of course, SO had another non-cash leg up: the blogs of Jeff Atwood and Joel Spolsky as major marketing avenues, i.e., the instant attention of large swaths of the developer workforce). If you don't have that option, regardless of if it's used or not, you play by different rules.

Stack Exchange is cool and everything, but it didn't have the same difficulties that face most bootstrapped startups.
