Facebook is where the clueless people are. Unfortunately, I love quite a few of those clueless people - so I join them where they are.
When all your friends decide to meet at that fake corporate fac-simile of a cliché pub, you go there too because you like your friends and might meet some nice girl there too. You may suggest a place with beer that does not taste like llama piss, but you drink that beer with a smile anyway because in the end it is all about people, even with stupid UI, satanic EULA and sprawling ads.
