I agree with minicole that "female" activities like pedicures are off-putting even insulting. I am watching my girlfriend, who is an accomplished artist, move into web development. She has a whole different set of values and weighting of those values than I do or do the male developers I work with. I firmly believe that there is a huge benefit in letting women apply their values to projects and letting them know that their values are appreciated. My experience is that this results in a more cooperative collaborative environment.
