I’m writing far more custom code lately (plugins and theme functions, really all the same) because when you start using wordpress as a full-fledged CMS, you’re dealing with bleeding-edge functions that have only barely been discovered by many (or are still waiting to be stumbled upon in the source itself). So there aren’t many plugins … Read more
