In case nobody has noticed it yet, there's an interesting new challenge on codegolf.stackexchange called "Showcase your language" where you can only show a snippet of length equal to your number of upvotes (more detailed rule there).

http://codegolf.stackexchange.com/questions/44680/showcase-your-language-one-vote-at-a-time-experimental-challenge

No D entry yet, but could be fun.
