Where does everyone advertise their themes?

I’m trying to get in to the marketing mode and advertise my themes as best I can. Does anyone have a few pointers for me? I advertise in the usual places… my website, DeviantArt, Creattica, Twitter and Tumblr.

Any advice would be awesome!

I don’t think it doesn’t need any advertising, tf itself is crawling with hungry mob of Customers tf is top 208 in the world website ranking in alexa. you could pay for Cost Per Click such as adwords,adbrite,etc.. but chances are they might look at different themes that are way better.
