Reliability? It took me around 15 minutes to create a site with Claude Code using GitHub Pages with custom domain and somebody else is taking care that it is always running. What is the alternative?
You could use Claude, or you could use one of many static site builders.
For me, there is a large relative (percentual) difference in the perceived cognitive load. Perhaps not a huge actual difference, but when you are running tens of projects, everything counts.
Now I am not talking about actual reality but the psychological effect. It might be that some shared hosting site is in fact more reliable than GitHub Pages.
Obviously, a blog that you just forget is not that useful, but last site I created using this method was an advertisement site for a book. I have several blogs where I write occasionally.
