Derek Powazek had a nice post a while ago on how to reward visitors who read an entire page:

When you’re designing pages – specifically content pages – what is the best possible thing that could happen? I mean after the user has bought a computer, gotten internet connectivity, figured out how to use a browser, and somehow found their way to your site … what is the single best thing that they could do?

Read. That’s right, read. And read all the way to the bottom of the page. In this business, a user that actually reads all the way to the bottom of a page is like gold. They’re your best, most engaged, happiest users. You know, because they haven’t clicked away. They did the best possible thing they could do, and now they’re at the bottom of the page. And how do you reward them?

With a copyright statement. Maybe, if they’re lucky, some bland footer navigation.

If you ask me, that’s just rude.
