The design of Post-Its is wrong. There should be a tab next to the glue-strip, so you can easily peel along the strip.
We think that we do something correctly and then by accident we learn simple change that improves it. Nice share.
"A Post-It’s easy unstickability is its biggest feature and its downfall. When you yank a note from the bottom, it curls. That curling is just enough force to lift the note off the paper, the whiteboard, or whatever it’s stuck to." What do the properties of the adhesive have to do with this? Nothing.
The properties of the adhesive are what separates one from a piece of paper.
Article missed to mention that the glue is assumed to be along the top edge in both cases.
It no additional information is given, everyone should assume the roation is the same.
I don't get it, you are still applying the force in the same direction. I mean if you rotate the 'wrong' picture by 90 degrees you will see that they are both the same thing
In the "Right" photo, the glue is at the top of the image. In the "Wrong" photo, it is at the top of the image too. The wrong movement detaches the glue from the center of the pad to the edge. The right one detaches it from the right side to the left side of the glue bar. Both directions are orthogonal.

Don’t rotate it. Sticky side is still along the top edge, but the peeling direction is parallel to the strip of glue, rather than perpendicular to it.
I have to use them the "wrong" way so sheets will feed through.
