You write a number of articles which have a common thread, a linear pattern which leads to a conclusion, builds a thesis. You put the articles together and you have a book.
A book is a product, it is not content.
You create a blog post, it exists on a linear time line with other blog posts. But the other blog posts are not read, just the one.
This is not a product, this is content.
Can a single blog post connect? Or is its purpose simply to draw you towards the other pieces of content, like hooks in velcro. A single one has the weight of morning dew, but together they become a powerful tidal wave.
But that blog post does not exist on its own. It is a tree that resides in the forest with trees that are exactly like it.
Much better noticed, if the tree stands alone in a meadow.
