Ya know, I personally don't spend much time on profile pages -- either here, Facebook, or any online forum -- but your insinuation that everybody who checks out info on such forums is "creepy" essentially indicts MILLIONS of those who do.
People tend to express themselves NOT because they want their lives to fade into obscurity ... and ne'er be responded to communication-wise...and these options just happen to be one current tech way to do that...
If you want to 100% ignore tidbits about people, fine...'tis a Free Republic world...but to advocate -- as you've done here -- to 100% ignore bits & pieces about people...is frankly an anti-humanity statement...
It’s less of a matter of looking at a page, and rather obsessing over it to the point where it can be instantly recalled (for the purpose of some relativistic argument).
