There you will be able to read up on Google's business practices and watch a few videos. They are quite informative and pretty well directly truthful to what I've learned about Google. They monitor you too much -- reminds me of "Colossus: The Forbin Project" or maybe "1984" to a certain extent. Personally, I do not have a Gmail, I don't have a YouTube, I use Bing to search, and I will never own an Android. Check out the site and make up your own mind.
(Keep in mind it is a campaign by Microsoft to promote their email client, Outlook. However, it has truthful facts on Google's policies.)
