Probably the one of the biggest repositories of of all things femdom is the truly massive Femdom Resource. With links to images, erotica and other femdom bloggers, it’s a good way to track down artists and writers. The audience it’s aimed at is mostly people who are attracted to femdoms, not femdoms, but the thoughtful blog is definitely worth a read. And, the commitment the creator has to the task is truly commendable.
On a smaller but more focused scale, Femmedom Book Reviews is more concerned with pleasing femdoms than the people who like femdoms. One challenge about the kink is that it is often done very badly- for example heroines sold as dominant who end up doing more submitting than ruling and Femmedom Book reviews is there to be your canary to help try things before you but them and then end up hurling the book across the room.
Also, I drew a pirate femdom. :3
