MySpace Is So, Like, Over

I've read this a couple of times recently, and wonder what it means.

"Over" as in nobody will bother to remark on its existence any more.

Or "over" as in everyone will hurriedly leave (to facebook or bebo?) and in a year's time it will be like wandering round a ghost town poking about in the remains of all the lives that were once lived there, finding dusty tins of spam on the shelves.
