I recommend everyone check out Storium on Kickstarter. It looks like a great driver for writing, creativity, peer editing, and more. Designed for online setting creation and storytelling, Storium has wonderful potential for many classrooms. I have already spoken with several teachers about its possible applications as a classroom tool. You will probably recognize the names of at least a couple of the authors that have thrown themselves into this project. It is doing well in its fundraising and, as of this writing, has eleven days yet to go. Have a look. You may want to pledge support and receive various perks, or you may decide to wait and see what it looks like on completion. Either way, I would enjoy hearing what you think of Storium.
Have fun!
