The myth of the page fold

Joe Leech posted an great article titled, "The myth of the page fold: evidence from user testing" proving that people actually do scroll down to find content. The article offers some good tips to ensure content below the fold gets seen.

This article got me thinking about how users scroll. What method do you use to scroll a page? Do you have a scroll wheel on your mouse, use the scroll bar in your browser, page down key on your keyboard? Let me know if my poll.
