I spend a lot off time in the site review section and one off the things i say a lot is this:
"...i don't like the white background you are using...."
and here is why:
1) I realy hate to think the web as something should look like paper.
Although a lot of webbuilders might started as paper artist (painting, making dtp designs, photographing etc.) the web is a completely different medium as paper and should look different.
2) White is boring as hell.
Ever been to somebody who has a complete white room?
It looks cold and chilly or like there is no one living in it...if you know what i mean.
3) The only thing i don't like is the white background, but that's becouse i really do not like white anyway.
Why? well i am behind my computer at night when the surroundings are a bit darker. On such moments white on a bright monitor gets really bright-white making it hard for me to focus. It is like looking into a lamp i guess. Personally i wil not use white on a light-emitting device, like a monitor or a tv, ever. But as i said this is me who realy hates white.
However if you think this site will be seen by people in a dark/gloomy room (for instance after getting home from work, they look in the evening) you might consider using a less bright color like light grey, light blue, creme, ivory or beige.
