> What's the benefit of going back to flat files?

Edit in your editor of choice. Use your source control for edit history. Trivial to keep a separate instance to edit/test on, and push with rsync. Makes it trivial to treat the code and the content as one unit, so that e.g. if you change parsing of the articles, update the articles and need to revert, you don't need to mess with reversing database updates separately).

Fewer moving parts. For a typical modern blog with comments farmed out to Disqus or similar, the data is likely to be tiny and very static. My blogs data, for example, is about 8.3MB of text that changes maybe a couple of times a month, so the 1-2 second cost of reading every article I've ever written in from individual files on disk is hardly an issue.
