Interesting question. It made me wonder whether the same questions are asked of other industries - do people who work at car companies drive the cars they make? Do people who work at cereal companies eat that cereal?

I bet the "eat your own dog food" expectation is higher for software than it is for a lot of other companies. It may be that people are still wary of a company that doesn't use the software it makes. But cars and cereal are so perfected and assembly lined, so to speak, that I bet few people question whether those companies do the same thing.

But maybe I'm wrong. It's a fascinating issue.
