UX isn't about who did what first. It's about doing what makes sense for the user, then reapplying it in every scenario that works. Pull to refresh on the iPhone was utter genius and everyone adopted it. No one is saying, "Well Tweetie did that first!" Also, it seems like a "no brainer" now, but during the development it's easy for these no brainer things to either be ignored or written off as a waste of valuable engineering time.
