So, why do I hate this so much. It looks like a great idea, it really does - what use is *just* a wheel? Or a car without a steering wheel?

A car meets a very wide range of requirements, a skateboard just a few specific ones.  What if the most important requirement was to be able to carry 3 large suitcases and 4 people 200 miles?  What's the first "prototype" there?

I think the answer is a pretty resounding "yes, of course". The reams and reams of substandard C# I see every week (mainly from code posted on the interweb) demonstrates the fact that people don't "pick up those things later on". They simply don't. How many code/function snippets have you seen on various blogs (mine included) which have associated unit tests? Hardly any. Don't get me wrong, I'm as guilty of ...
