Whenever I create a blog page, I want a "Table of Contents" module to open and allow me to drag and drop the new blog page link under any Text Heading or Sub-Heading of my choice, including a new Heading/Sub-Heading.
Tags and Categories are fine for Chronological Journals, but they are completely useless for blogs with a theme. Political Activism, Instructional, Concept Generation, even the Forums all require a Table of Contents so that readers can easily search for content that interests them.
A Table of Contents allows verbose descriptive text to describe each page in an organized manner.
For example: http://blog.360.yahoo.com/jamesbdunn?p=207
This is a Table of Contents; it can no way be compared to a Tag Cloud or Category list. Though the "software" for creating a Table of Contents is very similar.
