Communities of Practice: Learning, Meaning and Identity
Etienne Wenger puts communities of practice in the center of learning in this book. Wenger calls it a social theory of learning. It fits well with both my notions of knowledge (as capacity to act, and as a social construct) and the networks of meaning that are central to George Siemens' Connectivism. Needless to say I see lots of connections to social media as well (even though they were hardly conceived when this book appeared)
