Indeed. The author of this webpage: "Drabbleology" defines a drabble as a "prose poem."

Like most drabble discussions, it's aimed at the members of a particular science fiction fandom (in this case, the television show Stargate: One). But the author's tips and pointers (scroll down a bit) are chock full of good advice for any writer.

Personally, I find writing drabbles a wonderful cure for writer's block. When I give my dreaded Inner Editor the job of counting every word, she stops fretting at me about "breaking the rules" of storytelling (i.e.: "You can't have your hero do that! What would your mother think, if she knew?!").
