1st paragraph of this post- still no idea what this thing is. Presuming it's the drive copy program.
The rest of this post, still not clear. Probably not the copy program.
Blog post: ".. a great open source publishing platform .." -- ok, it's like Wordpress. Gotcha.
I've seen people complain about the submission for a product announcement being unclear before, but hearing that complaint leveled at the comments is a new one.
See e.g. Rust, which does this really well: https://blog.rust-lang.org/2018/08/02/Rust-1.28.html
Nope. johnonolan's post is top and it explains about as much as the site. Not much at all. There's an animated thing going on a page break down from the top, but the site is so jam-packed with marketspeak and vagary that it shouldn't be surprising. Also, I still don't know what it is. Compare that with Codesandbox (also on HN) which is straightforward.
