An addon would be cool, lets folk choose if they like it or not.

However, there are many blogs that separate a theme or topic using tags (categories). I think your missing an important aspect of blogs. Take a look at this post -> http://www.hyperorg.com/blogger/mtarchive/003571.html and I hope it will show you where the text blogs are going.

You don't really need an addon, just adjust your template to include the links that they require. We already have multiple categories, if you want to use them for tagging, everything should be available to you. If not, let us know.
