What do 'content aware, blog aware, ...' mean?

I see it’s told that it is blog aware. What does it mean?

“Blog aware” doesn’t really have a fixed meaning, but I’m guessing you saw this in Jekyll-related documentation too? Basically, a “blog” is a design pattern (design as in site architecture and not necessarily visual design) where individual pages are called “posts.” So, something like Jekyll has the default content directory called “posts,” in which each markdown file created = a webpage = a post.
Further, many blogs exhibit…

A. Two types of associated metadata: 1. tags and 2. categories.
B. A URL structure that emulates the publish date; eg, mysite.com/posts/2016/05/15/my-post-for-the-day
C. The ability to create drafts, modify publish dates, etc
