This is off-topic, for which I apologise, but I now find myself fascinated by the various ways in which gender is communicated. It seemed really very obvious indeed to me that Skatche was male; so much so I was vaguely susprised that the question had been asked.

I think it's a combination of the split of experiences, different writing styles (men /do/ write differently than women) and LW being a very male-dominated environment.
