Um, there seems to be a bit of a problem with the tagging for this theme. If you click the link in the post, it takes you to a page with a handful of images on it, but it you search "theme-workers" in the box on the top right, there are over 17,000 entries, a lot of which don't have any tags at all. Anyone know what's going on there?
The page with the handful of images is the one for this week's theme. Searching for "theme-workers" will likely turn up images that have the words theme or worker anywhere in the tag or the description.
