I'm currently working on a blogging engine I call bittyblog
https://github.com/cluoma/bittyblog
I'm not a professional coder so it's mostly a toy project to get me programming and learn new things but I also use it for a couple of my blogs and add features as I want them.
It's CGI/fastCGI based with SQLite3 for storage. It integrates well with lighttpd because of its fastCGI process manager.
