After the whole PRISM/NSA/GCHQ scandal I think there were two roads to take: make your internet life as secure and private as possible (I tried this, it was boring and probably futile) or realise that keeping information private is only going to get more and more difficult. If you come to the latter realisation as I eventually did things like this might excite you. The more info Google has on me the more exciting and useful it's products will be. I'm particularly excited about the future of Google Now.
Instead of giving up altogether, I suggest a different approach: choose your enemies and compartmentalize your personal data.
Stuff related to your personal life and your feelings? You probably can't keep it from the NSA, but you can keep some of it from Google and Facebook. Super secret work stuff (think airplane parts, not stealth mobile app startups)? Cryptography and all kinds of misdirection to throw off spies.
When Google knows a lot about me, it knows what cuisines I like, so when I search for "restaurant" it can return search results for restaurants I might like... except I could have searched for "<cuisine> restaurant in <place>" and the results would be good enough.
Current returns are too marginal and my own judgement is often better; future hypothetical returns may be matched by improvements that don't require so many privacy invasions — specialized search engines, for instance.

My approach is based on thinking ahead and of the future benefits I might get from Google knowing my private information (Glass, Google Now etc). I never thought that "future hypothetical returns may be matched by improvements that don't require so many privacy invasions". You've gave me something to think about!
