I am industrial engineer student at the Hamburg university of technology (TUHH). Since lately I am working on my master thesis about User Innovation (for the institute of marketing: https://www.tuhh.de/alt/im/home.html) and heard of TTN at the Maker Faire in Berlin. I asked you to participate in my survey here: https://www.thethingsnetwork.org/forum/t/survey-about-user-innovation/26698
Feel free to contact me if you have any questions.
