Long pages work. Just look at Wikipedia. In the 90s, we had a fashion where websites would cut up an article into 6 pages, 2 paragraphs per page, to get more page impressions. Luckily these days advertising runs on Pay Per Click more than Pay Per View (thanks Google!), so that practice is going away. But still, people seem to have a tendency to cut up good content, and often, they shouldn’t.
Look at this page for example. Over 100 comments, and what’s wrong with showing them all on one page? Sure, the page text is 116 KB, but that’s not too bad. And it’s compressed, so it’s really just 21 KB, which is fine and fast even for a dialup.
What it does is that it lets people scan over the conversation, scrolling, and get to the end and contribute their comment. If I were to cut those long comment strings in pieces, the experience would be worse.
Scrolling works. Long pages work. Anything else tends to be informationarchitecturitis (which I define as “the practice of adding too much structure when it’s not needed and even gets in the way”).
