This is still the same amount of duplication, except way easier to
parse. Docs nav now lives in `_config.yml` and you must restart jekyll
to see changes to that list (since config is only read at jekyll launch)
This will let us keep docs in order on the filesystem but have
reasonable permalinks. If we add something at 02- it doesn't result in
lots of broken links.
* All posts under blog/
* Index @ blog/index.html
* Only show excerpt on index with "continue reading" link
* Date, name formatting improvements (better for humans)
It could probably still use some style tweaks but I feel better about
it.
Moving forward, we'll use the "excerpt" feature of Jekyll with the
default separator, which is just 2 newlines. So the first paragraph will
be special. Alternatively you can specify excerpt, but we'll want to fix
the layout so that gets added in.
