Taboo Data via Ben Rothfield

There is a class of data that we can derive easily—but can only use very, very carefully. As Ben Rothfeld explains: "I heard you went to Victoria's Secret today" is OK, but "So, you like push-up bras" isn't. Complicating things: consumers aren't really all that comfortable with the idea that you know enough to target them, but when you do target them, you'd better get it right.

Great article from Ben Rothfield
