Buzz Anderson shares a design mock-up of the pull-to-refresh feature he and Neven Mrgan were toying with for their now-retired Twitter app, Birdfeed. This mockup pre-dates the shipping date for Loren Brichter’s Tweetie release, which included the feature.
I really like what Neven had to say about the situation:
Simple ideas like this will naturally occur to many people. A small percentage of those will have the ability to execute on them. A small percentage of those will then actually do so. And an even smaller group will combine it with an otherwise interesting product, thus making it into something.
