People that use average to describe the middle of non-symmetric distributions are dumb.

Thanks for the help here on this one! Dumb people will now know just how dumb they are before making misinformed assumptions. Really helpful.

I hope you realise the distribution need not be symmetric for the average value to be in the middle.

Yes, but elchief's point is obviously that if the data has a positive or negative skew, the median is going to be more helpful than the mean.
