Weaning myself off Facebook

Friends asked me last weekend why i only post things about motorbikes and boats on facebook. I did post other stuff, quite critical about recent developments world wide, before, but no more. Some reasons:

– for the last visa waiver for the US the online application form asked for my social network sites. Not yet a “must” input field. But nevertheless worrying.
– i was called a racist by a local internet user because i placed a video of a maniac bus driver in Manila going 110 km / h and changing lanes all the time very dangerously, and called the clip “Maniac Busdriver in Manila”.
– i just learned that somebody i know lost his job because of what he posted online.
– A few other similar things happened.

So only shallow stuff on my Facebook account. Talk to me for depth.
