I saw this mentioned once in the wordcount thread, but just in a passing way. I've been considering a try at writing some flash fiction in between drafts of my longer works as a way to clear my head before I revise. But I hate doing things that wouldn't be productive, so I want to write good flash fiction. To do that, I need to read more than I have (not hard, I've only read 3 or 4). Does anyone here read or write flash fiction, and if so, where would be a good place to ground myself in it? I'm afraid to pick a random source, because how do I know their relative quality? Thanks, y'all!
