The two sidebars together are not meant to be a mistake - I've put them there to see how they go for a few days.
As I usually have pics across the top of a post or on the left, this lends itself to the new format but there've been difficulties with the html. I can't seem to determine sidebar length and so it seems to cut off below a certain point and the text then wraps around. At first I thought this was not so good but it actually shortens the page, so I've left it.
Not being sure how it would look on Windows with IE, I downloaded IE5 for Mac and have looked at the page in Safari, Firefox and IE. Seems to be basically all right.
See how it strikes you.
