It sucks to have to learn how someone else wants you to work, and that's a big part of what a framework needs from you: to learn how to use it. Learning someone else's code is much less rewarding in the short term than writing your own code.

He suggests that your framework is better because of just that - its yours. You know how it works, the ins and outs of the features and how its been refined down to just what's really needed. He does point out, though, that:
