the other one that I don't like is when people don't even ask a question but give a command instead - such as 'Flip flops in the MDR - discuss' or one I saw recently - 'I have been considering upgrading to aqua - convince me' - I mean to keep the topic relevant -
'posting quiz answers is helping others cheat - tell me I am wrong' (this is an example please don't tell me as I don't think its true - I think it builds community and is helpful)
