It's more enjoyable all around to keep the tests and implentations small.

I've just barely attempted to pull off the TDD thing, but I was impressed at
the simple tests and short functions that came out of it. Everything felt
very orthogonal, and the code was easier to incorporate into a larger
program later on. I'm not totally sold on it yet (probably because I'm lazy)
but i'm impressed so far.

Part of why I think this happened is that simple tests trigger my laziness;
I don't want to have to write a lot of code just to do a little thing, and
that raises my standard for the straigtforwardness and ease-of-use I expect
in an interface. I become more user-centric.

I also think that the "refactor mercilessly" approach pushes a design toward
simpler, smaller, and more reusable units of code.

BTW, I had a hunch, and just as I expected, you're the guy that tipped me
off about TDD back in April. Thanks for that. =)
