How incredibly helpful! After reading this article, I have a much greater appreciation for the communities and how powerful they can be. With the correct planning, preparation, recruiting, and maintenance these groups can be very successful in generating great ideas!

I found this article very helpful! I just recently heard the term "community of practice" for the first time. This article truly helped me to understand that this is not a new thing by any means. A "community of practice" is simply a group of people coming together to achieve a common goal. As Dave mentioned, I also liked how the author explained these communities in the three components of domain, community, and practice. Nice find!
