OutShine is a Twitterzine edited by Jetse de Vries which publishes optimistic, near future prose poems. The catch with a Twitterzine is that each story or poem can only be 140 characters.
A few weeks back Outshine published one of my optimistic prose poems. Here it is, reprinted in its entirety:
Anyone interested in submitting to Outshine should check out their submission guidelines (and do note that they are a paying market). Outshine also publishes an excellent selection of insightful quotes, and is worth reading on a regular basis.
On a final note, Jetse is also working on the Shine anthology of optimistic SF. I'm writing two stories which might work for the anthology, but I won't know until the end of April if they'll be ready to submit.
