...your site can show up on your competitor's site. What isn't clear is whether that results in a wash or if there is something we can do to come out on top of the exchange, even if we can block the display.

Good points. This suggests that perhaps the wisest course is not turning the feature off in your own browser, but rather keeping it on and seeing what you can learn from it.

PS: I should add that I think this feature will provide Google with some additional sets of "nodes" to study as it charts user behavior in relation to its site and your site... with the choices pre-organized by Google in categories it would like to examine.

I'm wondering if Google's going to be sharing any of the exit data with us via Analytics.
