Maiden names, did you keep yours?

I was reading a blog and it raised a question about men wanting a boy to carry on the family name. It got me to wondering... did my women readers (I think my only readers...LOL) keep their maiden name or take on your husbands name and why? Do you think it is wrong, disrespectful, ect to keep your maiden name and not take on your husbands name? Or do you think its empowering to keep your maiden name? What do you think of men taking on their wives name? In this day and age, does it really even matter?
