I was a tester (paid in t-shirts) for the first color version of the Google logo on i-mode however many years ago, and I’ve never looked back. Gmail is the most important site/service to me, period. Some of the Google Suite is also indispensable. But my all-time favorite is Maps (and Earth).
Nothing else makes me feel quite like I lived through an important technological period than using cutting-edge tools with a huge initial wow factor which I eventually started taking for granted.
So beta testing new Maps features? Yes, please.
