It is with great sadness that I share news of Joe Armstrong's passing away earlier today. Whilst he may no longer be with us, his work has laid the foundation which will be used by generations to come. RIP @joeerl, thank you for inspiring us all.
The biggest web UX improvement right now would be to let browsers take care of this “can we track you via cookies?” issue – similar to how they already handle privacy-sensitive features such as location data and notifications.
