Google

As of March 1, 2012 Google will be collecting data about the user from their YouTube searches, Gmail, and Google+ to tailer your search results and have more ads that you are "interested in" depending on what you search. Also, you will be able to move across Gmail, Calendar, Search, YouTube, or whatever your life calls for with ease. Another difference is that when you share a document, Google will remember contact information of the people you share it with to minimize the amount of clicks it take to share with that person the next time.

In the article it says that Google will merge data from the products you use and the analyze it to make new assumptions. If you have an Android phone Google already knows your location. If you put your appointments in a Google calendar it also knows where you are going and what time. "That's not something I want my computer telling me. It's creepy," said Kurt Opsahl.

I agree with Kurt Opsahl that what Google will now be able to do is kind of creepy and unsettling. The thought of someone knowing where I am and where I will be going scares me. I think Google is getting way too involved in the users' life. I mean how easy is it to access what Google knows? Some creep could track you down by all of the information Google stores.
