Yes, Sarge, you observe correctly, imho.
I've always thought that FB it is a great idea to keep in touch with friends and family around the globe. When you have a free service I don't think anyone minds the service being ad supported.
For me, I don't care if FB had 500 million or 700 million users. If you're a marketing organization, you probably do care.
Perhaps people are getting tired of keeping up and liking everything.
