I like Kathy Jackson's thoughtful and informed Cornered Cat, which has a lot of information for women shooters. I recommend it to new shooters as well. For women considering self-protection from stalkers, etc., there's AWARE. And sometimes I find good stuff on Second Amendment Sisters.
Mas Ayoob teaches at Firearms Academy of Seattle, and also writes for some back-to-the-land online journal whose name is escaping me. I respect Mas, but he has that religious bias that leaves me feeling uneasy (I am obviously not one of the Elect in his mind, and probably part of the problem?).
