The terms used to describe the community blog posts is a bit confusing. Communities can publish a 'blog', which can be commented upon much like a typical blog-post in conventional blog engines. A blog in the conventional sense is composed up of multiple posts... but in CHEC-CESC the community can only publish a blog, that has no subtopics (only comments) below.
Would it be more consistent to say that a community publishes Posts? The Community Blog Page, where all the submissions are displayed, then makes sense as the collection of posts, and comments.
