It's not processable by third parties? If you tweet that you met me at a conference and then someone else tweets that you saw me at the airport, etc. now people can't use that to infer my location and travel patterns? You're just drawing the line conveniently where you can violate my privacy while simultaneously claiming the higher ground. I hope your friends treat you with the fear that they should considering you seem to believe that their private information is not "processable by third parties" and therefore probably treat it with no discretion whatsoever.
