CSS headings on blog posts too large

[dunnl]

Yeah, I'll do that. Maybe we can look into changing the CSS to make h2's a little smaller?

The CSS headings are a little large. I suggest we not deviate from semantic markup, e.g. second-level headings ought to be h2s. We should determine the difficulty of patching the typography settings.
(Alternatively we can add a custom class to blog headings with a Pandoc filter)
