It's fascinating! It would be great to have this information from just normal email -- the data's been there for many years -- but does it seem like privacy invasion then? There doesn't seem to be any difference...

My mail feels private, Facebook doesn't. A lot of people complained loudly when Google started scanning the text of emails to display "relevant" ads. My guess is, there will not be very many people complaining about this.

I suspect it only feels this way to you and me because we know better than to treat anything on Facebook as private, whereas email still feels like it at least should be.

But for my older relatives, and also for a lot of my friends on Facebook, I suspect there is no difference in their minds.

The mob only makes noise when shit hits the fan, the majority is either willfully ignorant or overly paranoid. Even among techs.

What if I'm mailing a friend because I don't like the item?
