I'm unable to find the specific company and website in my old emails, but I have seen an example on the web of what you're describing. The reader could select whether to expand or collapse sections (e.g., I want more detail on this subsection).

The web interface was similar to a medium blog post, but the amount of work for both the writer and the reader was more than I think most folks are willing to invest.

I’ve stumbled across something similar. It was a personal portfolio / bio site. The owner wrote several versions of each section, using different styles and level of detail. The various versions were selected by the reader with some sliders or something.

I thought it was pretty neat. A huge pile of work to write all that, but neat.

It's interesting if you consider the time spent writing versus time spent reading. This post will take me less than a minute to write, you less than a minute to read, but perhaps five/ten people will read it - a 1:10 ratio.

Popular content will have a much larger ratio - if I am a popular writer I might spend a day or two on a fancy blog post like described above, but if 60,000 people spend 10 minutes reading it that's 600,000 minutes - 10,000 hours! Now spending a bit more time to make it more useful/enjoyable/readable seems worth it.

Sounds like a job for GPT-3. The author writes the long form version of each section and then GPT writes the simpler versions.

This "depth slider" is called the Inverted Pyramid [0]. The first paragraph has the main information (aka tl;dr). The next the secondary points. And as a reader, you just have to keep reading as you want more details. You know the next few paragraphs don't have more important information than what you've already read.

That's how the print media wrote their articles. They've already sold the paper/magazine to you, so now the goal was to make you feel like you have as much information as you would like with as little effort as possible, so you're willing to buy the next issue.

Nowadays, with the attention economy, the writing style has changed. The main objective is to keep the user reading for as long as possible.

You already have a "dynamic slider control" for everything you read, it lives in your brain and it's called "skimming." Well-written articles already expose the essential point in an easy-to-find way, and I couldn't imagine what a "give me the tl;dr now" button would do to our already ruined attention spans. The tl;dr might exist for some articles, but most of the time, the essential point requires a lot of build-up and context to understand; you can't just take that context away.

To paraphrase you:

tl;dr: skim-read good articles, dummy.

Longer version: here’s a thoughtless snark ignoring that you said you wanted longreads and ignoring you wanted to dial complexity to 11. Society’s tuned to custard, get off my lawn.

Extended version: I really like to show I am the smartest, most condescending, person in the forum. Let me state the obvious. Nobody listens or uses their brains these days, because TikTok. Your idea of a slider is lame. Normally I would just ignore it, however I felt compelled to make a sweeping commentary on society and your inane comment was just the hook I needed. I really wanted to correct your spelling and grammar, and comment on your smell, but I did remember that is against the guidelines[1]. If would love to downvote you to oblivion, but even talking about voting is illegal on HN: long live 1A</sarcasm>. Ironic huh?

PS: Hopefully this amuses you: I am being facetious, but I am also trying to give you the gist of how your comment comes across to me, in my opinion. I am not a bad guy, and normally I try to write higher quality comments.

Just gonna say that your original comment definitely reads like the tone that you’re pretending to have here, so it might actually just be you.

Fair point.

I was trying for a playful positive tone. I will try harder, but it is difficult, eh?

I suspect the difference I have with the person I answered is that the primary interaction I have with Twitter is links from HN, which are often short, relevant and to the point. I don’t see the flames because I’m not involved with the fire.
