Readin Two- Search engines and internet tug of war

I thought the things I searched for were safe and personal; I didn't know that search engines (which I use alot) were invasive. Despite my awareness of the "crooks and crannies" in the internet, I think search engine companies shouldn't have access to and save searches done with their engines. I feel that my personal space and comfortablity with the internet has changed dramatically. I can't vow to never use them (search engines) again, I just think I'll have to be more careful with how I search and the words I use.
