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?
It can be particularly good in soft-paywall situations, where you want to give people a certain number of clicks per month before they have to start paying.
I don’t think I’ve ever actually seen these “keep reading” buttons used in that way, though.
