An aggregating post (AP) is simply a post that contains a list of links to other posts or webpages.
The purpose of an AP is to collect links to similar posts to make it easier for you (and others) to locate and access posts with one, two or three mouse clicks.
Let's say you create fifty (20) posts in your personal blog. You could click on "Your Blog" and see the full content of all of the posts, or you could add your initials to the "Keywords" section of each of your posts and then click on one hyperlink instance of your initials to see the title of all of your posts. But neither method organizes your posts. You create APs to do that - to organize links to your posts.
