I spent a bit of time mucking around with Ghost install on AWS, then toyed with an AWS marketplace - it was all a bit much.
$3.95 AUD (about $0.02 in USD - ok, not quite that) per month for two blogs. Perfect. Setup was very smooth. Just as easy as ghost.org. And with two blogs, the KoalaSafe parent blog and engineering blog are now separate so parents don't have to read about the latest OpenWRT version when they're trying to figure out how to setup screen time limits for their kids!
