I started this project hoping to understand how social media data is harvested, processed, analyzed, and used for marketing and political communications. While compiling this bibliography I read a lot more research than I could include, and almost none of it reflected any consideration of how it might affect human beings, communities, politics, or the natural world. It should be expected that other people will insert their own values into applications of this technology, for good or ill. And that's exactly what's happening.
