That was interesting! I am female, but I'm far from 21...a decade to be exact. But with what,"690,000 registered users in four years and is adding another 1,100 every day" I'm not surprised we don't hit the median demographics. I'm curious, though, to the realistic growth logistics, especially since this seems to be a system that by nature grows exponentially. He told two friends, then they told two friends, literally. Ah, well, I suppose the technology to handle the growth is growing just as fast. I hope. :)
