I couldn't agree more, and I'm glad to see you picked up on this.

I feel the same way. I'm far more comfortable, and have far more trigger time on one language over another, and those inherent nuances make me far more productive.

Of course it's easy enough to learn a new language/library, but that's not the point. The point is what do I know now, and what can I be productive in, the quickest.

Kudos.
