Stacey Kuznetsov and Eric Paulos at Carnegie Mellon University recently published results from their study into DIY projects, communities, and cultures. They said:
A year or so ago, we invited DIY enthusiasts from Instructables , Ravelry , Adafruit , Craftster , Dorkbot , and Etsy to fill out our survey on DIY communities, projects, and cultures. We received 2600+ responses in just a few weeks. Many many thanks to everyone who contributed!!
Our work explores DIY as a vibrant culture with a long history of learning, creating and sharing. We hope that our study inspires more discussion and future collaboration within and across DIY and academic communities.
