Aha—Facebook has issued a statement on the mysterious stalker feature that we spent all day covering: "Facebook tries to surface the people we think are most important to users to make it easier and faster for them to navigate the site and find what they are looking for...The search drop down is not a list of those that have searched for the user. It is also not a list of people whose profile the user has viewed the most or who have viewed the user's profile the most. To avoid any confusion, this will no longer appear." See, you were too stupid to handle it! But wait: as our commenters figured out in about one minute flat, typing a period (".") in the search box brings up the same five-person list. And are they really your "most important users?" Random. We urge continued experimentation.
