This will take some getting used to for me because the standard convention is not to include the final slash, but I think given that the pages all render at siteurl/baseurl/subpage/ (as opposed to baseurl/subpage/pagename.html) it makes some sense. And then the home link can just be {{ site.url }}{{ site.baseurl}} which is clean.

I'm using it without the slash in the notes repo: https://github.com/cogrhythms/notes/blob/master/_config.yml
so maybe I will end up changing one or the other to be consistent.
