It's a fact that scrolling is a moderately unpleasant activity, particularly for people with repetitive stress injuries or on alternative mousing tools, such as a laptop or kiosk mouse.
It's also true that if a home page takes a long time to load, people on a slower connection will sometimes leave. And if one has an advertising-supported stte, more pages looked at means more ad impressions.
On the other hand, with every site l've worked on, there is a severe drop-off in the number of people visiting the second page (usually around 75%) and another drop-off to the third (50% more). A page break is a moment for a person to contemplate, "Shall l continue?" If you've got a powerful message at the end of your article, there is a good chance it won't be seen.
