Did anyone try out Google's new Sites app? It's based on JotSpot (which they bought 18 months ago, AFAICT), which used to be a kind of wiki/blog platform targeted at intranet and other team uses. The Google Sites overview has an example of a classroom application of the Google Sites model (apparently in connection with Google Classrooms). There's also a mention of classroom use in a short demonstration video.
Now, this Sites app doesn't seem very feature-rich as a Content/Course Management System. But if this app is very easy to use, it could be useful as a kind of barebones CMS for classroom use. In fact, chances are that content created with Google Sites could be integrated into other systems, including Moodle.
