Well,it has always being about different strokes for different folks in as much as people really like posting their entire life both private and otherwise online for validation by total strangers I still thinks they are people just there for serious business.
Yes,a lot of people are just there to seek attention and show the world they have arrived posting irrelevant things that just doesn't Add up but Facebook isn't just about that. People I know are cashing out big time daily from Facebook.
There are a lot of money to be made from Facebook now,it no longer a platform for attention seekers,marketers, bloggers, vloggers,dropshippers,artists, publishers, writers etc are all advertising their skills and making good money from the platform so it not for attention seekers alone.
