Cultivating communities of Practice - EXCELLENT!
When I first order this book I didn't knew the author, but now... well now I recomend to all of the ones that need to understand and do some papers or work in the Communities of Practice field.
As I'm a Teacher in University I'm used to work with papers and books related to some thematics. This one is excellent because it explains step by step the things that usually don't fit in other books.
So, I recomend it to all of you.
