The scrolljacking + history pollution of this site is basically a crime. Also, is there anything more useless than a slide deck without the actual presentation? Just have to kinda guess all the blanks eh? I normally wouldn't even comment but I find data oriented design to be the best and love to see other takes/critiques/methods but this is useless as is.
