Why is user-select: none and pointer-events: none applied to the content here? In the DOM it's perfectly serviceable content, even if the divs are absolutely positioned to achieve the editorial layout. If you disable these CSS properties the text is selectable and pastes in the right order as expected, since its based on the DOM ordering which matches the line order...

Additionally overflow is hidden, so you cannot read the entire text on desktop without using a very small zoom... and as others have noted, mobile is fully and completely broken. If the bubbles weren't so huge at least you could read a paragraph or two on mobile.

Full of emdashes and AI comparisons like "The performance improvement is not incremental -- it is categorical" too :-\

Presumably because the DOM order of the elements is not the actual order of the lines (you can see this with e.g. the blockquotes), so it would be confusing if the user tried to copy the text and saw that all the lines were jumbled up

It's only the blockquotes that are out of order. If this were a valid reason to disable user selection, then no website with a sidebar would have it enabled. Besides, you could just disable user selection on the blockquotes if that were the reason (not that I'd ever recommend that)

That wasn't my experience, when I resized the window and new text showed up, it was completely out of order
