Myspace has long been parodied as the Jersey Shore of social networking: full of emo kids, aspiring "models" and generally everybody on the internet who has bad taste.
Facebook, in contrast, was born in the Ivy League. The pages were clean and streamlined (if for no other reason than the user had less control than the MySpace user). However, a series of changes took place, starting with the decision to News Feed. To wit, Facebook got a lot more cluttered. News Feeds OK, gaming apps OK, credit card ads - well, they're annoying, but every other website has them. In the past few months Singles adds have started popping up.
A website is a lot like a professional athlete or a Nascar coat of paint - the quality of the sponsors are reflection of the quality of the brand. So, LeBron and Nike (good for him), GlobalSecurity.org and credit card adds (...ehh), -- Facebook and Hot, Local Singles?!
This from a company that is reportedly worth ~USD 15b?
Facebook can try to squeeze every last drop of ad money it can, but if it does it must come up with a new social networking strategy - it can no longer be the clean-cut Myspace
