(Interrupting the story.)
When not thinking about Judaism, I'm trying to master the art of procrastination. To that end, please see the sidebar of this blog, where I've categorized all my posts with del.icio.us and got the topics to show up via FreshTags. If I were using a different blogging platform, I could add the tags within the application. But I like Blogger, so this solution will do until they decide to support tags. The only annoying feature of FreshTags is that after you've read a post selected via the dropdown list, you need to go back to the blog home page in order to access that list once again. It's still a pretty cool little program. I think del.icio.us tags are also picked up by Technorati, so I'm now categorized up the wazoo and can sleep well at night. I'm not sure why this makes me happy, but it does.
Update Nov. '06: Blogger Beta now supports labels, which I've applied to every post! Much easier, although FreshTags was great as an interim solution.
