Let's do a bit of an audit of Ghost RSS feeds vs WP RSS feeds, because there's quite a lot of difference at the moment. Eg.

http://john.onolan.org/rss/

vs

http://blog.kissmetrics.com/feed/

I'm fine with the two being different, but I'd like to make sure we're structuring feeds differently for the right (or at least some) reasons.

Are we using the correct tags? Are we missing any?
