take advantage of me, now!

Down in the murky depths of Darcy's commenting system, Kris Tiner asks a very pertinent question:

how far can blogging potentially be in (and bring others into) a dialogue with the actual music, be an integral part of it, rather than just a record or scrapbook of it...

I've been trying to think about how this blog should work (hence the poll, the listening notes, the quotes, the sidebar link feeds, etc.) and am very interested in ideas about the ways the blog format can fully take advantage of not being a magazine (print or electronic), a radio show or a TV show, but some kind of intersection of all that.
