I've been thinking about this, and haven't yet. I'm not sure how I feel about short stories. Novels have been my reading drug of choice for a decade or more, though I used to love Asimov, Analog, F&SF, Ellery Queen, and Hitchcock. But you quite got a few stories to read from.
I'm dithering whether to put up three backlist short stories of mine, or do them as an anthology. I think I'll go with anthology of all three, which will still be under 25,000 words (a little under a third of the word count of my romance novels, and less than half of my YA titles).
There's something about a good short story that is very satisfying, though.
