If you're running your blog on Jekyll, you may have noticed that generating RSS feeds requires a little more thought and effort than other blogging platforms. That's why I started a GitHub project to share my liquid templates for RSS feeds. A couple of them are universally useful; others are particular to site's setup, which I've noted in the README.
I've had to incrementally tweak these feeds since relaunching my blog back in May, so I imagine they will be useful to someone out there. Let me know if you find these helpful.
Oh, and contributors are more than welcome.
