Google Incognito Private Browsing (2008)

Do not use those Incognito (aka Private Browsing) feature. It basically just delete the browser history on your computer.

• It does nothing to hide the fact you visited the site.
• It is useful, only if other people share your computer and you do not want them to see what site you visited. (that is, it does not show in browsing history)

Google created the feature around 2008 and promote it, in a way misleading you to believe that nobody knows you visited a site.
