Use the post's author from frontmatter, or else use the author from
the site's config. You MUST have one of these set or else you will
get an error during site generation. I think it's better to force
the user to define an author tag rather than only printing it if
it is defined because it is a good practice to help bots understand
content.
Use the post's meta description if it exists, otherwise use the
one from the site's config. Set them using the "description" key
in frontmatter or site config.
Note: this means there is no way to NOT have a description. You
must have *at least* a site-wide description and *optionally* a
description for each page/post's front matter.
The W3C's HTML5 documentation says that header strength (h1–h6) is
only important per section, but their validator[0] recommends only
using one h1.

Headers are a semantic element that help computers understand the
content. In general, header tags should follow rank order, but the
most important is that the first header inside a section will serve
as the title in a table of contents, etc, but since article sections
stand alone as independent documents, I like the idea of explicitly
starting with H1 tags.

The HTML5 <article> tag represents a complete, or self-contained,
composition in a document. Headers are a semantic HTML5 element
that helps computers understand the content.
Partials are nice, but blocks are a better base construct. Right
now there is basically only layouts/_default/baseof.html that is
doing most of the work.
