This final note today, a comment on the value of being left alone, or at least not being observed while you’re online.

The folks at Gallup have done a new poll. Overall, about two-thirds — 61 percent — of Americans don’t want advertisers to be able to target online ads based on one’s web-browsing history, even in exchange for more free content.

That varies generationally, as you might expect. Older web surfers are more protective of their information than younger ones. Here’s the best part, though. In every age bracket and at every income distribution, 90 percent of people say they don’t pay attention to ads anyway.
