@P.J. Morse It took a long time to make enough money to be able to make this our full-time job. For quite a while, we were making more than beer money, but less than rent. We didn't really feel comfortable in quitting our day jobs until we sold our first book, which gave us a little cushion, financially. Ad sales-wise, we used to be with (and still have some) Blog-Ads, which were GREAT for us. We're currently with Spin Media, which does our ad sales and hosting and provides our photos as well. People occasionally think they own us, but they do not.
Thanks everyone for your kind words! I am really looking forward to seeing the next interview in this series.
