"Guests" or people who are not logged in also bump the counter, but do not show-up on the list of names.
Back to the OP, would you just want to know who has visited your profile or also how many times that person has visited? The order in which they visit or just that ABC viewed your profile X times? Of course, until your profile is showing at least 10 names, you pretty much know everyone who has visited. If the names don't show up now, I don't think they would under your proposal.
