Members of the Systems Sciences WG have always enjoyed open access to a reliable platform via this Google Groups list and the Google Site. (Thanks, James Martin, for taking the pragmatic step in 2011!)
For people who are interested in continuing to share openly to the world,
Benjamin P. Taylor (with
SCiO in the UK) and I are partnering on migrating the previous model.report and Systems Community of Inquiry participants to
http://stream.syscoi.com , hosted on Wordpress.com .
There are two levels of participation.
This platform is the next evolution since the major shifts from Systems Thinking World on LinkedIn in October 2015, described at
http://coevolving.com/blogs/index.php/archive/towards-a-federated-social-web/ . We've learned to be less bleeding-edge on our technology platform choices, and have a primary concern for preserving collective intellectual capital in the systems thinking community.
