Do Not Track, Ads, and the Free Internet

Apparently forgetting Adblock, host-file ad blocking, DVR 30-second skip buttons, mute buttons, VCRs, remote controls, and the queer idea of getting up to make a sandwich, various people are predicting the end of the "free" ad-supported Internet, this time from people honoring "do not track" instructions. Also, some teachers in Ontario are afraid of Wifi, MIT launches a fully automated online course in electronics, and the EU dabbles yet again with the disastrous idea of a "right to be forgotten."
