If you enjoy this sort of thing, you should check out another Twitter account, @DailyMicroFic, who has been doing this a lot longer than I have. Through them, I discovered the the #vss365 hashtag, where you can find lots of people writing very short stories on Twitter, 365 days a year. See vss365today.com for more info and daily prompts.
I enjoyed writing these. They were a fun exercise in writing under severe limitations, and the format gave some life to lots of little ideas I’ve been kicking around for ages, but I hadn’t been inspired enough to expand into longer formats. I think I’ll have to do it again sometime.
