The idea of it is if you comment, you will be featured. Featured deviants will have 2-3 deviations (Art, Literature, Etc) that I liked from your gallery displayed with your feature.
If you comment, I wouldn't mind a feature like this in your own art feature journal. Of course, I don't mind either way.
The idea isn't to get free art features, It's to help spread artists and their art around.
