Facebook
It had to be here didn't it? Facebook is without doubt one of the most annoying things about modern day technology and culture. Facebook has taken away an under-appreciated part of life from us to some extent. Real human interaction. Nowadays if you have a Facebook profile then it sort of becomes this trap that you can't get out of as people will develop an annoying tendency to contact you via Facebook rather than by phone, admittedly, I do that myself. Those annoying people who post a status every 10 minutes either complaining about men or a status containing irrelevant song lyrics. All those unfunny "like" pages do my nut in as well. Maybe I'm just bitter about the website, because it cost me my job a couple of years ago. Word of advice, don't add people from work.
