Google knows the content of all of my emails. They know what I buy online. They know what I search for on the Web. They know what videos I watch on YouTube. They know where I'm driving, how fast I'm going, and where I stop to eat on the way. They know I have a doctor's appointment on my calendar Friday at 3 pm. They know I searched for "irritable bowel syndrome" today, so that's probably what ails me. They know what medications I've already tried because I've Googled the potential side-effects. They know who my friends and family are because they're on my contact lists and in my Google+ circles.
They know all of this and more about you too. Apparently you don't care. Good for you.
Well first you have to realize - Google doesn't give a crap about you. And I mean that they don't give a crap about who LagunaSol is. Get over yourself as if Google is actually READING your email and caring about the fact you googled IBS. At most - you're a quick blip to them as part of aggregated data so if wonderdrug x wants to advertise, Google can say - oh - we have x% of users who have googled that. We can target your ad.
And for someone that hates google so much - you sure use their applications a lot, don't you?
Lastly - Google is such a small fish to be concerned about. You want to lose sleep tonight? Go read up on Axciom. They make Google look like amateurs.
