This where you are wrog and didn't read the author proposition. In the article the presented Sococo products is in 2D, and if you refers at actual usage, like slack, you stay in a 1D (list) of users, so form me (rare) products like sococo are goind in the good direction by adding 1D. 3D is perharps one too far goal, but in the mean time we should explore 2D as much as we can and radically change the ay e make web app, instead of trying to (pale) copy the (master) slack.
