The new site is definitely optimized for the new layout.
OK OK I'll turn off legacy.
But in truth, there are nuggets of good information hidden in posts that at first glance i would not open, so I'll just miss them.
For example , I'm not really going to open up the Macy's pop up sale post. However, the information about the lip balm is pretty good to know, and if I wouldn't open the post, I would not know that nugget of information.
