The Systems Community of Inquiry is a worldwide network of systems thinkers, scientists and practitioners.
This SysCoI Stream was migrated in January 2018, based on an experiment started at syscoi.com/stream in June 2017. These instances have been based on WordPress O2, a communications tools first used internally by WordPress developers in 2009, extensively revised in 2013, and then released to the open source community in 2015.
This site also archives the content from model.report at https://syscoi.com/model.report/model.report/newest.html
The expected advantages of WordPress O2 over Buddypress are a simpler interface, and a lower maintenance.
