> Bizarre how you seem to think someone else owes you answers to questions you don't seem to want to try and answer yourself.

This, of course, depends on your goals, but if your goal is for your project to reach more people for whom it is relevant, it is not crazy to provide some basic motivation.

"Why anyone should use this" is the fundamental question that anyone building something with the intention of other people using it should be thinking about. For example, Pi agent provides lots of information on the thinking and motivation behind the design. Even if I don't use the project, I come away learning something interesting.
