The Craigslist home page is an example of bad IA. The lack of images and white space cause a blur effect on the page.If you're not familiar with the site, you may have to scan the entire page and read all of the links in order to find what you are looking for. There are dozens of links on just one page alone that gives a user too many options to look through all at once, and too many choices can be overwhelming. It'sa good idea to limit the number of things to look at on a screen, like seen in the examples of good IA above.
