If you’re a hacker in the free software world, or just interested in that world, you’ll probably like this book as much as I did. Biella Coleman is an anthropologist who did fieldwork in the Debian Project and studied the politics, ethics, and culture of the free software world. In other words, she analyzed us. Who can tell a fish about water? Apparently, an anthropologist can, because the results are enlightening and thought-provoking — as well as just plain enjoyable to read.
Update 2012-12-31: There’s an excellent and thorough review by David Banks up now. He’s obviously very familiar with the academic landscape Coleman works in, and the impact her book should have there, but both the book and that review are accessible to non-academic readers (I am one) as well.
You can get the book from Princeton University Press.
