1. In CatB, does Raymond assert that debugging of open source projects is more (or less) difficult than with traditional development methods? Why?

He says that debugging is much easier with the open source model.

Reasons: Given enough eyeballs all bugs are shallow. Debugging is parallelizable. Someone can find a problem, and someone else can fix it. With hundreds or thousands of debuggers, every problem will be simple and obvious to someone.

2. In my essay, I argue that Fetchmail and Linux are not really bazaar-style projects. What do I claim that they are? Why?

I say that these projects are actually cathedral-style projects.

The reason is that they have one single architect, with lots of helpers. This is just the way that actual cathedrals were built.
