Facebook's only real use is scoring chix, and finding where to score chix.
This is irresistible to most.
While I don't have a facebook myself.. i don't consider spending a great deal of time on facebook a waste... The people that do so are just fulfilling a biological need.
Look at the alternative, Spend a huge amount of time Traveling to potentially fruitless barren locations to meet women.. gasoline + unknown time expense
Facebook, has reduced these costs, and made light of the happening hotspots where you're most likely to score..
and it has made pre-screen targeting possible, You can estimate what the girl is selling herself for, and select based on comparison with what you're willing to pay..
I'm not talking about direct prostitution, but facebook and dating in general is in fact Indirect prostitution..
Facebook has significantly reduced the "connection" cost of dating for men. This is fantastic..
What is lost in "productivity" they claim, is made up for 10 fold by reduced resources spent to HOOK UP.
