Smaller

I think I'd be inclined to write the whole thing in one chunk, since there are still a few people without MTV/blog-tuned attention spans, but then blog summaries of the major point and sections, and use the comments for each blog entry as discussion links from the main essay.

It's a bit odd that no other blogging tools have borrowed Radio's idea of stories (a generally longer entry that you write through the same interface, but that stands on its own outside the time-based flow of the blog, with as I remember an optional autogenerated notice posted to the blog).

I've seen Radio users make good use of that functionality, and it did strike me as a good idea. This is the sort of thing I'd like to have separate from the rest, but I don't want to go to individual-entry archives.
