Given USMC, EU, China and TPP proposed regulations FB has probably entered the toaster for industries. This has happened before and more companies than FB will be regulated out of existence. So, how soon do you think this will start?
Interesting. What regulations killed Myspace?
I think it just happens.
I have two trains of thought on the subject.
Myspace became popular when more folks online were "tech geeks". Facebook got popular as the internet went mainstream. Facebook is less customizable so tech geeks with falling snow backgrounds didn't look superior.
AND/OR
Facebook has/had a cleaner design and some dose of reality to it which more folks liked.
