I discovered two cool things today that have to do with WPMu and tags.
First, that WPMu 1.3 (and WP 2.3 for that matter) comes with a stock widget for a tag cloud that doesn’t require a plugin or anything. How did I discover this? Well, UMW History professor Sue Fernsebner had it in the sidebar of the class blog for her Cultural History of Late 20th c. China seminar (which also has possibly the coolest header image I have yet to see on a blog). So, if you are running WPMu 1.3, look for the Tag Cloud widget, and drag it to your sidebar and behold the wonder of tagging without using categories.
Second, I found a solid plugin on wpmudev.org called MuTags. This is a simple solution for tags on WPMu, and what I particuarly like about it is that it gives you the option to create a tag cloud of all the existing tags as well as the existing categories — which is very cool if you have been using categories as tags as UMW Blogs has for the last semester.
I really think that tags add that extra functionality for aggregation across classes for student blogs that make the whole portfolio/aggregation idea that much simpler. A larger post in and of itself, but I’ll end this one by saying that the possibilities for tags in WPMu 1.3 has some amazing potential.
