Very welcome. My adamant attitude (which occasionally get me in the doghouse) on this topic is that we should own our data. With strict exemptions (FICO collection of credit behavior comes to mind - as bad as that tastes) Individuals should be the owner of their data. Personal information (data is a misnomer) should have similar restrictions on how it can be released as with medical history,
by consent of the owner.
Will I miss the sharing and collaboration with family and friends? Hell yeah. But to me, it's a worthwhile sacrifice. And yeah, I know almost every web site pimps my old ass, but some pimps are less abusive than others....
