Information+ has been postponed for one year, until fall 2021.
Hopefully, in the fall of 2021, a new version of the conference at Georgia Tech will be carried out with as many of the existing components as possible.
There is one positive update: the special issue of the Information Design Journal with contributions by presenters of Information+ 2018 is now finally online under an open access license: https://benjamins.com/catalog/idj.25.1
