That's an interesting theory, but what I really want to know is how you prove that. Reddit has a culture that came, in large part, from the founding of the site and the kind of links that people submit (which started out as bots posting stuff at the founder's direction!), which at least superficially, sounds a lot more reasonable than "women and the elderly don't use the site because UI".
