Some article websites (I’m looking at msn.com right now, as an example) show the first page or so of article content and then have a “Continue Reading” button, which you must click to see the rest of the article. This seems so ridiculous, from a UX perspective–I know how to scroll down to continue reading, so why hide the text and make me click a button, then have me scroll? Why has this become a fairly common practice?
Maybe to make the article seem shorter, so you’re more inclined to keep reading. Once you’re halfway through, you’re more likely to want to read the rest. Both halves are probably filled with ads, so the longer you stick around, the better.
