It’s an interesting thought experiment, and something that I could working in practice. At the same time, I’m somebody who tries to find flaws in concepts, and granted, this is a first draft so I’m probably digging a bit too deep for critique here, but you mention:
“· For the user, it removes friction because deciding to read a story doesn’t take her away from the list, only at the end. It’s likely that a user will end up reading more stories per session.”
While I agree with what you mention I, personally, feel like this might be a double-edged sword. From my own experiences I know that quite often, when I just open up a bunch of stories/put them onto a “read later” list, by the time I get around to reading them, there will be one or two that I’ve lost interest in in the meantime or, especially with current affairs, there will already be a follow-up. I don’t have a professional insight when it comes to this (yet), so this may just be my perception of it, so I’d be interested in hearing your thoughts on this.
I also just now realized this article’s 3 years old, whoops!
