Don't Muck it Up with Junk!
Don't confuse your audience with a lot of mumbo jumbo like ridiculous amounts of graphics, videos, or links as far as the eye can see.
Basically, just keep it simple, stupid. Nobody wants to come to your page and be shown a total eyesore.
Technology is Great, So Use It!
The days of lame websites should be long gone. HTML has advanced immensely and we now have XML and CSS available to us. So we should certainly use them!
It is amazing what you can do when creating a web page! Simple things that bring it to a whole other level of professionalism and cohesiveness.
