Two reasons:

1. I'd imagine the first thing most people would do after standing up a scaffold is rename the site to customize it. Before, it was hard coded in the layout. Putting it in `_config.yml` makes it easier to find and makes the on boarding experience smoother.
2. If we put a variable in `_config.yml`, the template site then shows off all the core features of Jekyll templating. Could very easily walk someone through the result of the template site, and they'd have a pretty solid understanding of of Jekyll works.

Not :wedding: to the idea if you have a strong opinion to the contrary. May just be an artifact from my WordPress days. :smile:
