"One thing that’s cool about Tweetie 2 is the fresh paradigm to refreshing the contents of a table view. Up until now we had been looking for space to mount a reload button on, sometimes having to resort to adding an extra tool bar for just one view so that you can have enough space. Now if you have a tableview that it sorted reverse chronologically, then you have a natural urge to make new items appear at the top by pulling down the table with extra force.
Loren recognized this need and innovated the Pull-To-Reload paradigm. If you want to refresh a tableview in Tweetie 2 then you simply pull down the table far enough for an additional cell to appear at the top with the instruction “Pull down to refresh”. If you do, then at a certain point the arrow rotates and the text changes to “Release to refresh”. All accompanied by two distinct wooshing sounds and a pop once the reloading action has ceased. The Intuitiveness of this paradigm is so compelling in fact that people who use Tweetie 2 start to try to refresh ALL tableviews like this."
When someone innovates people start copying. Or just taking inspiration, they say. But when an innovation becomes a standard, are we sure it's good at all? Where's the difference between an innovation that gets copied for good and something that gets stolen for the trend's sake?
