The Data Liberation Front  
My Feb 10th post cited the lack of data portability as a concern. I stand corrected - Google has an active and thoughtful initiative - The Data Liberation Front - that lets you extract your data from Google and take it with you.
Such initiatives can only come from an open culture that encourages active work on innovative ideas and an enterprising spirit. Of course, being a wildly successful business that derives its revenue from an entirely unconnected segment viz. advertising, helps too :)
None the less, I love Google for the incredible, high quality and seamless computing it provides.
