Very interesting paper, thanks. What it seems to bring out is how important social considerations are when you choose a name for your child - what other people will think of the name, and who you want to impress, or for your child to impress. It's not just a personal preference - 'that's a nice name.'
I remember arguing once with a friend that the same applied to the choice of cars (ours is a Toyota Auris), but he was unconvinced. He insisted that he chose his cars on purely objective grounds: price, performance, reliability etc.
