I have a humorous, near future, optimistic story up at the twitter magazine @Outshine. For those of you linking to this blog from there, welcome! Take a look around, you can find some posts about writing, science fiction, and some advice from the pros on worldbuilding for the short story length.
For those of you unfamiliar with @Outshine or twitter fiction in general, basically they publish stories that are 140 characters or less. There are a few of them out there, paying and for the love markets.
If you would like to follow me on twitter I am @jonrock.
