This is my biggest issue with Facebook. I was once a moderately active Facebook user, back when it was cool and before it became ubiquitous. Over the years, without really thinking about it, I've allowed my Facebook friends-list to accumulate dozens of extended (and my entire immediate) family as well as professional colleagues and many other miscellaneous acquaintances of various walks.
I was once fond of posting interesting articles and commentary, but now I am compelled to consider the politics/religion/sensitivities of ~250 individuals lest I end up in a flame war with my aunt or boss or individuals who I've been actively avoiding who are suddenly pissed because I made a FB post but didn't reply/comment/like their relationship status update.
Facebook has managed to make social interaction online more uncomfortable than real life, and as a result it's been over a year since I've made any type of visible activity on Facebook, but I still can't escape...
Socializing in the real world, I have to explicitly state things like: "Hey, please don't geotag me to this pub, and don't post pictures of me chugging this pint of Blue Moon".
In conclusion, fuck Facebook.
