Agreed, but tracking is different than sharing. Nobody's going to complain that your web server logs GET requests (well, not from an HTTP standpoint, at least), but posting that information to your social networking profile is a little different.
That said, there are certainly very similar cases out there already. For example, when you read a thread in many forums (vBulletin, at least), it updates your public (or semi-public) profile to say you were last seen reading that thread. I've never particularly cared for that either.
