Honestly, the new redesign is terrible in so many ways. Speed is one of them. Another is the waste of screen space. Finally, the image driven format just changes the whole dynamic of the site, from reading to scrolling. You can still find quality discussion in the comments of some subreddits, but the way users interact with the site is far more "instagramm-y" it used to be. The site is, overall, less interesting, if more "engaging".
