Here's an article on the Top 10 Fantasy Novels by Female Authors. The good news? marthawells is on the list! The bad news? seanan_mcguire, Lynn Flewelling, Naomi Novik, Robin Hobb, CS Friedman and Lois McMaster Bujold are all criminally absent!
On a semi-related note someone linked to a page where someone was trying to put together a list of feminist space opera.
Finally the "Geek and Gamer Girls" parody of Katy Perry's "California Girls" has apparently been around for well over a year, but i only found out about it at BayCon last weekend. (Hmm, apparently, the girl cosplaying as Han Solo is a another good reason to finally get around to watching the Guild =)
