As 'Like' Buttons Spread, So Do Facebook's Tentacles

When you click a Facebook "Like" button on other Web sites to tell your friends about a cool band, favorite political candidate or yummy cake recipe, you may know that you are also giving intelligence to Facebook the company, which makes money through targeted advertising.
But did you know that even if you don't hit the button, Facebook knows you were there?
That's because the "Like" and "Recommend" buttons Facebook provides to other Web sites send information about your visit back to Facebook, even if you don't click on them. Since these buttons are now all over the Web -- about 905,000 sites use them, the privacy-software maker Abine estimates -- Facebook can find out an awful lot about what you do online even when you're not on Facebook.
