Yeah, I have to agree with dillinger. It's a cool idea, but it really doesn't work as well as the previous format. I imagine quite a lot of work went into it though. I looked at it in Opera, and the appearance is OK, but still too wide for 1024*768.
In my opinion, the previous layout of aminet was one of the most user friendly sight I have used. I think all amigans love it.
edit- One can use 'fit to window width' on Opera, which works well for this. Displaying the page in 'user mode' also works, and allows one to choose text/background colours.
