Really interesting article. Thanks.
I like the comparison between traditional corporations and communities like SSC. I wonder how many corporations try to form communities within themselves to encourage the sharing of ideas on a variety of topics. I have worked for a number of corporations that encouraged employees to become a part of their larger community by participating in community projects, being active on things such as a school board, or volunteering for local causes. However I have only worked for one corporation that also encouraged the formation of internal communities (across departments) to foster communication and both personal and professional growth.
