I'd freak out if that second example from the feature-list would happen to me while I was browsing some site. "Hello I see you are having issues finding the 'free account' button?" ... "are you spying on me?"

edit: ok, maybe not "freak out" but i'd certainly feel at unease. Specially if it was a site enabling some form of PIM/im/private-ish activity.
