Well, well, well. Another smart trick of Google to collect privacy data from you volontarly.
Why would you ever want to save ANYTHING anout your web surfing on their servers? Why would GOOGLE want you to store it there? What could it be used to and for? Selling it to advertisers?
How is search going to be affected by it? Is SEO going to be obsolete? How are they going to show results? Related data? " You searched for blowfish, and we found all these related searches with blow-job, blow-up......"
Are they going to use it for, lets say, measuring the sites people visit, how long they stayed, did they go shopping, interests?
I am SURE I will NOT use it, but I guess there's a lot of ignorant people who will use it :(
