Five people who search you most on Facebook?

Go to your facebook, type a period into the search bar and wait a moment. Five names should appear in the dropdown bar. Don't press enter, just wait for a list of names to appear directly below the search.

Gawker reports that there are a number of theories about who these 5 people represent, but the first and clearly the best of these is the "Five people who search for your name most often" theory. The next most plausible (albeit less exciting) one would be the "Five people YOU search for most often" theory.

Do this quick before it's gone! Feel free to comment on which theory you support. My own results would indicate that the original theory has the potential to be for real.

The list is apparently now in alphabetical order, and apparently Facebook sent a reply to Gawker saying that:

"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."

So do we believe them? Or do we continue speculating about what it might have been? Given that this post has received more replies faster than any other I can remember, probably the latter...
