The only time I've been on a radio call-in show was in 2007 when some NPR show was talking about the acquisition of Doubleclick by Google. I was acquainted with Doubleclick because they were notoriously privacy-invasive (notorious among Slashdot-reading nerds) and when I called in I started with something like "Doubleclick is fairly well known as a kind of sleazy operation --" and the NPR talking heads cut me off instantly and went on to talk about something else. Since then the invasive tracking and profiling that Doubleclick pioneered has gone on to ruin everything about the web.
I WAS RIGHT, NPR.
(I'll be shown to be even more right if we ever learn as much about what Google's up to as we have about what Facebook is up to....)
