I wrote a free-market economics textbook for kids and posted it on Peerhub! (How do I enter this in the raffle?) I am so excited about this! Selling an econ book for digital currency is such a perfect way to do it. I also wrote a post about my Peerhub listing, but I don't want to spam your comments. I used a #peerhub tag, and I hope that's an actual thing. :)
