I stopped after the 4th click, I found it irritating to have to click to get 1 or 2 sentences at a time. This would have been just fine as a short article, making it interactive annoyed me more than the revealed content informed.

Made even more annoying by the "next page" button constantly moving with the page height.

Very annoying UX, I found it felt like it was breaking continuity and making the ideas on each page disjointed.
