I've had a blog[0] on GH pages for a few years now. I wrote a few posts about how to go about setting up feeds/og tags, GA, and I really should write another one about setting up everything else.

Basically, hosting a static blog is a rabbit hole. Keep track of where you came from, and share it out there. It's kinda amazing what you can do with a little bit of effort.

Personal plug: I cofounded Feedio[1], which gives you a widget for doing email subscriptions (among other things).
