I used Ghost.org in a project last year and love their business model (and obviously their product). Completely open source software, but you can pay a reasonable amount for managed hosting and support. Plus obviously it supports the devs and new development. A simple line to separate DIYers from anyone who wants the convenience, peace of mind, or to support the project itself. Would love to see more of this.
