Today I saw the digital equivalent of the slipsheet record, you
remember, you'd cut it off the back of a ceral box, or else it would
be blown into a magazine?

A daily free newspaper had a paper disc that popped out of an ad, with
a data cd in foil on one side. I dismissed it because of the content,
but now I'm kicking myself because I didn't grab one. What is this
stuff?
