I'm sure that most people reading this blog via RSS are here mostly for the PHP content. The recent spate of economics and government-related blogging is probably feeling like a bait-and-switch to many of you. For those of you interested only in the PHP-related content, you can subscribe to the PHP-only feed here: http://paul-m-jones.com/blog/?feed=rss2&cat=2.
Are you stuck with a legacy PHP application? You should buy my book because it gives you a step-by-step guide to improving you codebase, all while keeping it running the whole time.
