The Internet possesses and endless and continual discussion about a million topics.

A blog post is the author's prompt to gain focus in the ongoing (and evergoing) discussion to a particular topic, and relative to the author's given position.

It's like a button sewn into the conversation fabric. It's also part of the fabric and it has a little more gravity than a comment thread.

That's a beautiful analogy.
