Here's a half-baked idea, or more of a packet of yeast dissolving in some warm, milky water really. Wordpress started as a blog engine. A user would post, well 'posts', and these formed a stream or feed, but as more people wanted a system for general online publishing, the system was adapted to become a CMS. The little CMS I built for myself many moons ago, and use to this day, was designed to crate and manage pages and page-content, and now it occurs to me that it would be quite handy to be able to adapt it in order to be able to create a feed.
So, what next? I suppose I should start by defining what the feed should look like - the components: title, date, etc.
