Avoid putting things on your page that might distress or confuse your visitors. And avoid doing things that look different when viewed with different browsers, operating system, hardware, software, etc, etc, etc. Don't put me in front of that textured background. In the Olympics, they award extra points for the 'degree of difficulty' in sports such as diving. On the web, however, you get points for aesthetics, content, and ease of use.
Degree of difficulty counts for little if anything.
Nervous newbie Dear Webby, I'm working on my first web site. It's almost done, but I'm afraid to show it to anybody. Suppose I've committed some terrible faux pas that will have me ostracized as a newbie. Even the most accomplished webmaster commits an occasional faux pas. The good news is that the web, unlike real life, gives you a chance to fix your mistakes.
