I've handled the hiring of almost all Web developers within my company for the last half decade, and in that time I have hired absolutely zero women. Yet, this has nothing to do with discrimination and much more to do with the applicants themselves and the numbers by which they apply.

During this time, I've seen Web design positions attract females applicants by about a two-thirds majority, whereas Web development positions attract only one in twenty (if that). And yet, those who have applied seem to fit into two distinct categories of undesirables:

First, the designer, with a design degree, who learned to code from some two-week academy that now feels the need to apply for a position well beyond their skill level. Or second, the mathematics major (or similar) who feels their knowledge of topics only related to programming in general is satisfactory enough to hit the ground running as a Web developer of all things...

So I'll be happy to discuss the potential of a wage gap if I ever seem to hire a true female Web developer.
