Quartz
If you don’t know Quartz’ Obession newsletter already, I recommend you check it out. One very specific thing or topic, often somewhat offbeat, in the spotlight. This new one on post-its is great. I finally understood how (exactly) post-its stick – until they don’t.
From Weekly Filet #265, in February 2018.
