Although I don't think I have all the ingredients yet, I am throwing everything I got so far, including topic mapping-as-blog-contribution and Emergent Markup Languages, into the cauldron that sits on my shoulder and let it simmer for a while.  One thing that bothers me is the the difficulty with updating static blog pages.  Majority of blogs are static outputs from blog tools.  Inlining might do the trick, but there are UI, security, and style issues.  Oh, well.  I'll think about how I am going to set the table later.
