These days there are lots of anthropology sites, blogs, and projects that are really changing how (and where) people can learn about and discuss what the discipline is all about. Here are some of the most interesting projects out there:

Neuroanthropology is a PLoS blog that's run by Daniel Lende and Greg Downey.  From their about page: "Neuroanthropology examines the integration, as well as the breadth, of anthropology and neuroscience. Sometimes we do straight neuroscience, other times pure anthropology. Most of the time we’ll be somewhere in the middle."

The Open Anthropology Cooperative (OAC) is an online network of anthropologists that includes students, professors, and anyone else who is interested in exploring what anthropology is all about.  For more about this project, look here.

The Memory Bank is Keith Hart's online.  More here.

Savage Minds is a group blog that covers a wide range of anthropological themes and issues.  From their about page: "Savage Minds is a collective web log devoted to both bringing anthropology to a wider audience as well as providing an online forum for discussing the latest developments in the field. We are a group of Ph.D. students and professors teaching and studying anthropology and are excited to share it with you."
Living Anthropologically is run by Jason Antrosio.  The site description: "Living Anthropologically promotes anthropological research on biology, archaeology, culture, and language. Anthropology's moral optimism addresses contemporary issues in the public sphere."

Zero Anthropology is the creation of Max Forte.  For more, check here.

In 2008, Richard Baxstrom, Todd Meyers, and Peter Quinn published a book called "anthropologies."  This site shares the same name--and inspiration from the same influential anthropologist: William Roseberry.  I named this site after Roseberry's "Anthropologies and Histories," and it turns out that Baxstrom was one of Roseberry's students.  Serendipity, no doubt!  Check out their publication listing on Amazon here.
