My Barbannoy today, I was playing an online game mocking internet behaviour (forumwarz) where you go to a board and troll threads until you've pwned them, and one of the posts in this spoof game was 'How can we ban this idiot if we have no mods?!' which was so horribly reminiscent of this place I had to stop playing...
I annoy myself when my first response to someone saying they didn't understand something is to tell them I found it very, very straightforward. Needlessly pedantic. Thankful for the "back" button.
