Welcome to mobile where the only thing you can count on is change.
When a new medium borrows from an existing one, some of what it borrows makes sense, but much of the borrowing is thoughtless, “ritual”, and often constrains the new medium. Over time, the new medium develops its own conventions, throwing off existing conventions that don’t make sense.“A Dao of Web Design”
[t]he control which designers know in the print medium, and often desire in the web medium, is simply a function of the limitation of the printed page. We should embrace the fact that the web doesn’t have the same constraints, and design for this flexibility. But first, we must “accept the ebb and flow of things.“A Dao of Web Design”
