I’ve updated the tags on this blog.
Since July, 2005, I’ve been using SimpleTags by Burble, which was just a simple <tags> tag embedded in the content. Having upgraded to WP 2.3+, I can use WordPress’s built-in tags and the ecosystem around them. This mean I can use the Simple Tags plugin by Amaury Balmer (same name but no relation). This is good as I can now use tags as they’re intended, i.e. as categories, so if I blog about “xyz”, you can click on the “xyz” tag and see all posts about “xyz”. There’s also a tag cloud avaiable in the sidebar. Good.
