I was bored last weekend, so ended up taking a busman's holiday and created a simple PHP blogging framework sans database. Each post/article is written in markdown and stored in the "posts" directory, using a naming convention. It actually works: http://charles-reace.com. 
Not sure how it will scale with lots of posts, and for now it only works when deployed in the web root directory (opened a ticket on that 
).
Feel free to take a peek, chuckle a bit, then get on with real work: https://github.com/nogdog/cwrblog
