I passed on this article at first, but then this week I was searching for flights and found Google providing its own travel agent service allowing you to book flights with Google ("Google will securely pass your traveller and payment details to the airline"). It was nice - Google had all my information and had pre-filled all the forms except my destination and flight selection. But should Google be able to insert its services between yourself and your search target? What would we say if, say, 'Google University' offered to book courses with selected partners to people searching 'learn philosophy'? What about job search firms?
