Some background reading for those who read this title and went "Huh?!": http://en.wikipedia.org/wiki/Gender_identity
A few people have approached me and pointed out that there are people who identify as neither male nor female, and our current binary selection on the Drupal.org Gender profile field excludes them. Since it is quite literally impossible to create a drop-down that lists every possible value of gender identity, we kicked this around in IRC and came up with the following proposal:
Another idea that was kicked around was changing this field to free-tagging, but that strikes me as a data integrity nightmare given what the issue tag vocabulary looks like. :P So this solution feels like a pretty happy medium.
CiviCRM is one application that ships with Male / Female / Transgender, so there is precedent for this out there. And "Other" is a broad category that can encompass everything else. And "None of your damn business" folks can still leave the field blank.
I'd like to go ahead and make this change, but wanted to put it up for discussion first.
