Web 2.0 and the potential for collaboration across vast networks of practice bring about an interesting twist to Wenger's idea of a community of practice.
Peer-to-peer learning, collaborative learning etc etc are all interesting concepts and with enabling technologies are revitilising the principles of this type of learning.
Would love to hear from you.
