Web site #1: Site maps

I found that site maps are much more difficult than I was originally aware. It is certainly a useful tool to understand how a website functions. The more complicated a site map is, then necessarily the more difficult a website is to navigate. An expansive and detailed site map of a major site would take up a lot of space. A lot of space like 15'x30' I'll bet. Especially if the site map was to indicate header use and all the fine bits of info on every page. But that would be more the most helpful, because one could then see how well the site was organized.
