They are potential new visitors, and they will likely go to the front page. The front page should cater for them.
billswift seems to me to be arguing that "everyday visitors" (which I interpret to mean frequent users of the site) should bookmark or remember other site locations or other ways of consuming site content (eg. the many RSS feeds available), so shouldn't be much concerned for the usability of the front page to them.
If billswift is right, the front page should be optimised for new visitors (the group you seem to be talking about), and not for returning visitors.
What if the front page looked a little more like this?
