I also advocate for plain language and showing the product not just talking about it.
I guess what I would say is that the pop.work* landing page seems to want to sell itself as scratching an itch or solving a problem, but doesn't tell us what that itch or problem is or even show us how it solves it. It's just vague and no details (which is a major red flag about a landing page for me personally).
*lots of alternate "popwork" out there and you don't even link it or anything so I had to google text from the landing page in the video to find what and where it even was or if they'd completely pivoted to a different product (popwork.com)
You do the reader a favor if you get to the 'why do you care' part immediately, because in fact it may turn out that they don't.
Documentation eventually turns into a data warehouse. There's so much of it and you can't keep it straight, so some memorable fraction of the time, going to a Wiki page or your bookmarks or - god forbid - browser history. It's basically a fishing expedition. You know that there's a thing that did X, but you don't remember which thing it was (and code names make that basically impossible), so you're just going to scan a bunch of them until you find the right one.
If every page is like those cooking recipes that are held hostage by the life story of the creator, you're going to get pretty grumpy. Landing pages remind me a lot of this, because I've looked at twenty tools and I can't remember which one is for Postgres backups and which one is for Javascript minification. No, this one is for JSON. Next tab.
Here's why the web is a mess:
We've turned it over to Google, through search, and Google penalizes sites' rankings in search results for having Chrome users leave if they read the first line and realize the site or service isn't for them.
After all — your site is less engaging than the site that most users ended up on — right?!
Also I don't know about you, but when I'm researching something I open a new window, and I middle click all the reasonable looking links on the search page.
My time with that tab open has nothing to do with that tab. It's mostly to do with the tabs chronologically before them, and whether I see something shiny that distracts me.
It's like you're walking down the street and bums keep handing you shiny wrapped presents. At first they all look shiny and you want to open it but then you've opened enough of them to know they're probably full of shit.
So I stop bothering opening them. No, I don't want to create an account and give you my email so that you can spam me for months merely to know what's inside the box. Frankly my next stop is finding a video on YouTube of someone actually showing how to use... whatever it is. Or people talking about using it in a forum or something.
