I like your revamped idea and you don't have to compromise your intention if you team up with others. People are hosting lots of storytime stuff on Playa that you can join. Check out the PlayaEvents section of burningman.com and you'll see lots of stuff. I'm actually doing two Storytime events and need Readers, so feel free to contact me about reading at my event (info below).
Tuesday August 27th, 2013 noon - 3:00 p.m. and Thursday, August 29th, 2013 noon – 3 p.m.
Location: Prometheatrics' Dome at 7:15 & Esplanade
Contact Email: Phoenix.email@example.com
Remember that Storytime before Nap Time when you were a kid? Spend hot o'clock (12:00pm - 3:00pm) in the shade of Prometheatrics' dome while listening to various Readers share their favorite short stories. Feel free to bring your own story to share and make sure to bring something comfy to sit on, should you desire something softer than carpet-covered Playa.
