This system is designed to be used chronologically, each day's posts flowing down the page in the order they were written so that you read the day from top to bottom just like a page in a book. That's also why the Daily RSS feed is recommended over the Live feed. Blogging, however, is traditionally reverse-chronological with the latest post showing first so you always have the latest item in view as soon as you visit the site.
This key difference (along with posts not having their own page) is what would likely put people off using something like this.
As I went to bed last night I started mulling it over and decided to add 'Post Order' to the admin page. While the blog structure (each day to a page) won't change the post order on any given day can be specified according to preference. When post order is changed the post direction indicator (top right) also changes to point in the direction of post flow.
It's early in the implementation and I haven't looked at how it will affect everything so whether it actually makes the final cut is currently undecided. Still, it's a nice idea – it's always good to provide options.
