The WSJ discusses the milder Senate version, which it says would require scrubbing of data (rather like a pollution control metaphor for carbon sequestration, perhaps), to the point that not many parties would try to comply.
It also considers the practical threat of spying on ordinary commercial and personal (or expressive) activity online remote, and copyright or trademark infringement matters are supposed to be excluded, Still, it can be hard to trust that the line is drawn in a reliable place. Tides shift. And Some elipses are annular!
One other little thing in the WSJ today. An article warned Facebook users: "If you don't pay for something, you're not a customer. You're the product being sold."
