It is not always a good thing to have your web history publicly available. I have a Google account and disabled my web history there. You can do it by logging into your Google account, go to your account settings and choose to pause your web history. I prefer not to have a Facebook account due to too many privacy issues. One has to be very careful on social networking sites, because your activities there are available on the Internet for a very long time. I use Twitter and Tumblr but am very careful about what I say or do there.
