When you swipe your finger across the screen in most iPhone applications, you get the option of deleting the item you swiped across, such as a message in Mail. Some apps change this gesture to do something else and that can work really well. In Maps, for example, swiping across the screen moves the map. But with an application like Tweetie (yes, sorry to pick on you again, Tweetie), which looks like Mail and has a list of items like Mail, things can become difficult. Tweetie can become confusing, for example, when the swipe gesture brings up multiple options, like replying or opening the profile of the author. There should thus be more uniformity across the apps when it comes to swiping. With Tweetie, the swipe motion should do something similar to deleting.
