'Populars'?

Okay there was a lot of talk going around the OC about the 'Populars'. So I decided to investagate, :] all the questions are Who started it? And who 'are' the populars? Really I don't think of this group of people as 'populars' I just thought them as the 'group-who-alot-of-people-like-and-come-online-alot'! so I say some were thinking the same and then decided to call them the 'populars'.
