I disagree, it most certainly is a privacy issue. You may share a computer with friends, room mates, and significant others. If someone had access to your facebook account they could read all your messages, but this is something we are all aware of. Up until now I was _not_ aware of the fact that someone gaining access to my account could actually discover which profiles I frequent, which is like having a browsing history I did not know about, which I cannot even clear/remove after I learn about it. This is what makes it problematic.
