Not especially obvious down there.

The overwhelming majority of Web sites have a link to their "home" page right at the top in an obvious spot. So that's what most of us expect. I'm a Web designer who pays attention to standards and conventions. Having a "home" link at or near the top of the page is an almost universal convention. Everybody sees the tops of pages. Not everybody goes all the way to the bottom of every page.

Usability research has discovered that most people never see information that isn't in the first screen (meaning the first part of a page they see when the page loads - usually the top of the page). So important information should always be included in the first screen.
