Marketing Help

Hey all,
I'm new here but this seemed like a good place to start. I created a social photography website around the concept of the 52 week photo projects and I'm looking for ways to market it to other photographers. It's starting off as a way to encourage photographers to take the time to work on projects rather than just single images and to keep them on track with the help of reminder emails and image ideas. If anyone is interested I'd love some ideas for how to market this and/or take a look at the site http://www.52pixels.com
Thanks
Adam
