There is an aspect of web development that is largely ignored. It's called microcontent. Odds are that even though I've told you what it is, you still don't know what I'm talking about. Like I said ignored. All of these things need to convey what it is they represent in a concise yet comprehensive manner.
Web surfers have notoriously short attention spans.
If you confuse them or in any way make the experience on your site any more difficult than it needs to be, they're likely to jump to the next site without a second thought. Microcontent is the first thing that your visitors are going to see. Make sure it does its job, and make sure it keeps them at your site. I'm going to limit this discussion to navigation menu items and in-text links, as they are the two types of microcontent which most directly assist a visitor with navigation through a website. The navigation menu is key to helping a viewer through your site.
