And it's gone! It appears that the mysterious Facebook stalker feature—that allowed you to call up the names of five people who (we think) were searching for you most, just by pressing the down arrow in the search field—has been disabled. Our post on the feature went up shortly after 1:00; by 4:30 (or possibly earlier, based on our comments), it was no longer working. They're quick! We have an email in to Facebook to find out exactly what happened. How could they take it down without even explaining what it was? They mystery is eating us up inside. We will find the truth. [UPDATE: As noted in the comments, it looks like simply typing a period (".") in the search box will still bring up the same list of five people. Hope is not lost!]
