What happens when this blog breaks?

This blog is built by exporting a Tinderbox document. Tinderbox is awesome and I've been using it for years, but it's not really meant as a blogging engine, even though it works well as one. One day I'm going to upgrade or accidentally change something and the whole thing is going to go pear-shaped. Do I want to live under the threat of that happening? For now, I do.
