I set this site up using Ghost's blogging service.
First Ghost(Pro) gives you about the same service as installing the software on Google Cloud for less money and less hassle (no need to worry about your updating or installing).
Secondly, you can still tweak the HTML just the way you like it.
Thirdly, it's cheaper than you expect with a 10% review discount(!).
Fourthly, it's open source, there's no lock in. Plus I have learnt quite a bit from looking through the HTML (CSS3 animations ftw!).
Lastly, it's a pleasure to use and to look at when you've finished a post. As an amateur web designer the experience has given me some food for thought.
