That was what I was thinking. A dating service for devs is going to be like 99% guys. On the up side, though, it might underscore the benefits of having a more diverse tech industry.
I get what a few people said about not wanting to be talking about work all the time, but for me, it's more about shared passions. I'd much rather be dating somebody who understands why some hack I did is particularly clever, and maybe even has a better one. I have trouble finding any real chemistry with people who aren't part of my world.
