Oh how we wish that there was a "middle-finger" button instead of the thumbs-up "like" ones for all of those attention-seeking statuses, smug dating pictures or annoying Facebook updates. Well, Hater is the next best thing. An app that allows you to share all the things that get your goat, whether it be politicians, self-obsessed celebrities (yes, you Justin Bieber) or the French. Get hating. Humorously, we don't condone cyber-bullying -- though we'll make an excxpetion for Bieber.
