ok, rarely do I visit a site the bothers me so much that I feel the need to preach. When designing a site, there are certain things that I try to advise against for one main reason. Load time. If someone visiting your site needs to wait for even a couple seconds to see what you have to offer or what you are all about, they won't.
In a photography magazine, I came across a screen shot of a very clean and simple designed site. I visited the site and the design quickly fell apart as I had to wait for each image to load.
If you want to visit the site, go to
