Google knows more about you than you think and makes quite a bit of money selling this information. A seemingly innocuous web search on for example – prostate cancer can follow you and have very unwanted future consequences.

“Nothing to hide so nothing to fear. Whats the big deal?”

“I don’t really care much about Google tracking my results and why should anyone care?”

At the very least, what Google knows about you affects the results returned to you on your web searches. More disconcerting – Google employees may access this personal information. Are all Google employees honest ? Google gets hacked – yes, it does happen.

There are many more, some you need to know something about what you are trying to do to use them effectively, so I won’t include those.
Or, pay a few dollars a month to use a proxy server. It’s money well spent.
