70 seconds to load a chapter? That&#x27;s a terrible benchmark for even for some of the heaviest websites out there!<p>This may not be a popular opinion but I (and many ordinary readers like me) see that link as a website. Not a book.<p>It feels heavy and overwhelming to see a large number of 3D diagrams and visual depictions on just one web-page. Having to scroll down to read the full chapter with all that animation and &quot;motion&quot; is probably a bad move too. Given that this is supposed to come off like a book you can probably ditch the scroll.<p>Ideally, you&#x27;d want to give away few concepts in small easy-to-understand chunks with just 1 or 2 figures per page. And let the reader flip&#x2F;click over to the next section like it happens with an ibook or kindle book or even a real physical book.<p>IMHO the idea of ripping apart a book at its spine and forcing the loose design of websites over it is a complete no-go for avid book readers. Especially for the mobile and tablet users (probably even for the desktop users!, why else would everyone insist to download PDF, ePub or other artifacts?). But I&#x27;m sure that a section of developers over here wouldn&#x27;t agree with my opinion. So take it all with a pinch of salt.<p>Also just the place where I&#x27;d let the designers take over.
