> Does anyone feel a tinge of guilt using the amazing technology that Google provides?

I do and the same with a few other big company technologies and frameworks. It's not so much the support but more the fact that in the past a single person / small team could make a technology that became a staple of the industry. I always liked that it was one of the few things left that big corporations didn't have a strangle hold upon. Now however it seems that it is no longer the case and all the new frameworks, libraries and other such things are coming out of the big corporations - I guess I just enjoyed supporting the little guys.
