Question about tracking.... I have wondered.... Facebook has my email address and I use it as my login ID. Many other sites also use my email address as login ID, too. Even though I don't login in through FB but I use the same email address as a FB login, am I exposing myself just as though I though I logged in through FB???? Jeez, what's the answer? Do I need a new email address for each platform I use as a firewall? "userid.FB@gmail.com" for Facebook, "userid.TW@gmail.com" for my Twittering, "userid.LI@gmail.com" for LinkedIn, and on and on and on....
