Very interested in developing/supporting an authoring environment for OER for content experts on our campus & elsewhere (see https://medium.com/@steelwagstaff/core-principles-for-an-open-authoring-tool-db2df933dd8 for some views on the topic). Currently using Pressbooks + H5P + hypothes.is (hosted with Unizin, a higher ed consortium) and leading some development efforts around Common Cartridge, LTI, and Caliper Analytics.
