Saw the post on the Coase Theorem and the Gmail/GM scenario. On the assumption that someone looking for the Gmail site, upon arriving at GM, would continue on to the correct Gmail URL, we pulled U.S. data on visits leaving car manufacturer sites going to Gmail.

Unless of course, your ISP is spying on you.
