There've been many bad things. The collapse of loads of economies (Greece in particular), Norway shootings, UK riots, Japanese tsunami, deaths of Steve Jobs, Amy Winehouse and Gary Speed...
but then the deposition of people like Gadaffi, bin Laden, Mubarrak has been quite exciting.
Personally it's been a fantastic year though. Got into university, have had an amazing time so far and met some hilarious, lovely people, and got some of my reviews published on loads of music websites
