Hubs are crowd-sourced and curated by researchers, educators, students, and other interested parties and shepherded by a Hub Manager.

NKN has been established by the Open Network Alliance.  Open Networks is a non-profit social enterprise incorporated in Pennsylvania. Open Networks provides support to Hub Managers including the creation and embedding of a Hub specific Twitter feed and YouTube channel.  For more information on Open Networks, being a member, and Hub features, go to this post.
