WHAT IS A DD ( OR, DAILY DEVIATION ) ?
A DD is special recognition DeviantArt awards daily, to a few carefully selected members whom they feel their artwork should be brought to the attention of the community at large. It's a very high (and coveted) honor. ! ^^ Chosen deviations stay 'featured' for an entire 24 hours, and additionally, receive a permanent ribbon of recognition on the chosen artwork stating it is a Daily Deviation.
Did you know that anyone can suggest a daily deviation? If you see a wonderful work - or gallery, which you feel worthy, and that you think others might enjoy as well, just make your suggestion to the appropriate CV (community volunteer), shown in the link below, who handles it. Additionally, one can suggest one's own work to be featured. In fact, DeviantArt encourages that we do so; for who better than one's self, to promote one's own artwork? And many self suggestions have indeed been selected.
