Honestly, I don't like it :-)
The current design is very simple and clear, and very, very nice.
The work in progress you linked to us use a weird green and rollover effect on the button is not so good (not only because of the white on green text).
I can't see the point of using two big green bars on each side of the content.
Oh, by the way, I really hate the blog too :-)
But much important is the software, it is great and I love it :-)
