Before the term blog came into popular usage I had my own "personal news" driven by a PHP script that I wrote and backed by a MySQL database. I eventually gave it up after long periods of posting inactivity. Will I be able to keep it up now? I don't know for sure, but I'll give it another shot.
I'm planning on writing mostly about my experiences and thoughts about my work and my hobby, software development (specifically, development of web-based applications). It's unlikely I'll share anything completely new or ground-breaking, but hopefully I'll be able to note some of the lessons I've learned along the way that will be helpful to someone else.
