I've had success with a few micro-stories ... a couple went ka-boom for me last month. They can be good to mix in with longer stories/articles I believe ... part of the mix. I've found that racier stories do have an audience but I'm also writing a bit for a new pub I started that's going to focus on a "mountain town" mindset. More G and PG ... so, we'll see. You've built quite an audience, too, and I think that's a major part of anyone's success here.
