Things to Destroy in the fiery pits of Mt. Doom: Fandoms grouping around those pairings that you hate, your fandom dying, having to repeat a single game mission 100 times, thinking up good titles, thinking up good usernames, word limits, bad characterisation of your favourite character, writing a thirty chapter story for the only comment to be 'WHERE THE FLIP WAS 'THIS CHARACTER'?!?!?!' people asking for spoilers to your fanfic, suddenly having people upstage you in two subjects simultaneously.
