Sure, glad you found it useful!

A few months ago, I created a silly little sudoku site, then blogged about how I did it with no database backend (man, I got flamed). Truth is, I really didn't need one but lots of people couldn't see past the fact that I wasn't using the conventional database approach. In their minds, there was simply no reason why I should have used a few flat files.

The whole idea of databases and flat files is such a polarizing topic. It's terribly interesting.
