Great starting point, I'd love to see females on there. Not sure what it takes to meet the developer status, but you might have good luck with lovely ladies like @divya, @leaverou, @Sunfeet22, @stephaniehobson, @zahnster, @denisejacobs. To toot my own horn, I'm @_mandynicole - a front-end designer - even though I'm not a big Twitterer.
