They link to the RSS feeds for this blog. If you clicked on one of them up until an hour ago you would have seen some raw XML. If you don’t write code for a living, you may have assumed that something had gone wrong with the site. That’s because XML isn’t intended for reading by people, it let’s programmers write applications that can process data from different places in a simple standardized way. Anyway, click on one now and see what happens!
For the more technical minded, I’ve added a stylesheet to the RSS file so that users who inadvertantly load the file in their browsers get a short explanation of what the file is, and what it’s used for.
