A few years ago when I started to Waymarking I had an idea of creating a category about a person (in this case was an architect) and brought the discussion to the forums (the old ones that were lost) and it was almost consensual that it was not a good idea, and that in the future it would 't be a good procedure to create new categories about individuals and those that existed were from the beginning of the Waymarking.
In relation to a category where the criterion for inclusion is gender, in my opinion it is not a good solution. Here where I live there is much discussion and controversy about a new law about what they call positive discrimination, the problem with this is to have positive discrimination it has to be negative disctimination on the other side, they say is parity in numbers. (If a person one of the best in is area of expertise competing for a job together with a person who is bad at the same expertise, may not be hired not on the basis of his quality but because of is gender .) To me the society should not be forced but educated to eliminate any type of discrimination by gender.
I hope my thoughts and information on the local controversy will be useful in this discussion.
