Does it bother anyone that your online activities reveal so much about you? I've heard a story about a woman who defriended all her friends on FB because she thought that they revealed too much about her. And that search engines retain so much info about what you google. She said some will let you see your profile, but they won't allow you to delete it. This kind of bothers me. I think there is a search engine that does not retain your search history, but I'm not sure of the details. I think it's called duckduckgo. Anyone use it?
