Clearly defined areas

A website that I find myself visiting every once in a while is www.download.com. It's a good website for finding free software and shareware.

What I like about this site is that there are clearly defined areas. For example, if you're looking for software relating to spyware, you know where to find it because there is a category for it to the left of the page. Also, there are a number of sub-categories for each category as well. I think that if you can easily find what you're looking for, the website definitely has good design elements.
