I just posted a blog post from the new Office 2016 Public Preview (below).

It and this post too were made using the new Word 2016 Preview. The interface for posting from Word hasn’t changed much from the Office 2013 experience, except for the obvious colour difference on the Ribbon (at least as of today’s release). I look forward to trying out more features and functionality with Office 2016 Public Preview.
