Has Facebook reached (and passed) its peak?

I’ve gotten the feeling over the last couple of months that Facebook has began it’s decent in popularity/quality. There is spam and illegitimate services all over it, everyone and their brother has a profile (far from the old college-only days), and it seems to get more and more trivial and silly, with pages about everything and anything. Has Facebook reached it’s peak? Has it come to the top of it’s popularity and will it now become a vile, unorganized social website like MySpace?
