Jekyll gives you a lot of bang for the buck (including making static assets relatively easy to deploy) and Github provides syntax highlighting in their hosted service.

The drawbacks (as far as I'm concerned) are that Jekyll is overly temperamental, and that even "modern" site generators like Hugo (http://gohugo.io) require switching off too many defaults or tweaking many knobs.

Besides, even if you _now_ feel ease of editing is less important, a couple of years down the line it will be paramount.

I've long felt the need for something "better" myself, and run my site off a Dropbox-synced folder using a custom engine (which I'm currently re-writing - see demo site at http://sushy.no-bolso.com).

But I'm OK with reinventing my bit of the wheel (it's been nearly 13 years now, so I know what I want from a CMS).
