sigh I switched back to WordPress literally five days ago and haven't yet gotten around to installing a caching plugin. My bad. I've turned Cloudflare caching on in the meantime.
In June I migrated to Ghost simply to try it and learn more about Node. It was _fine_, but never really fit my mental model of how a blog should operate or a web app should be structured. For better or worse, I'm an ex-Yahoo and a PHP guy through and through.
