How often do you find yourself updating simple content on client sites e.g. posting up a news story? I'm finding a lot of clients just don't want to touch it and just pap everything over to me, despite CMS training etc.
Finding a CMS like WordPress a bit pointless when developing in this case, in fact the last 3/4 sites I've built have been put live as plain old static files.
Going forward, for the majority of projects, I can see Jekyll being my go-to. Obviously for more complex projects something like WP might be necessary but for the most part it's becoming less relevant to me.
