Beyond the question of how meaningful these metrics are, wouldn't it be a more useful metric to look at how complex the code you write when you use each framework is, rather than the code that implements each framework?

I suspect -- but don't know -- that these might even turn out to be inversely correlated for some types of frameworks. DSL-based frameworks often require some interesting tricks to get right.

So which is better? A complex framework that lets you write simple, concise code? Or a simple framework that requires a lot of boilerplate and complexity to use?
