AreaCellphone.com has posted a fun list of the 10 most idiotic iPhone apps. They range from Poop the World (which lets you keep a public record of where you've, aah, well, you know) to Hold On (which lets you see how long you can hold your finger on a button on the screen). Kiss Me lets you find out how your kissing rates by kissing the iPhone screen. Since there's no category in the App Store for Idiotic Apps, it's interesting to see how these apps are categorized. Hold On is in the Productivity category. Yep, you'll definitely be more productive if you succeed in holding a button for several hours. Kiss Me is in the Sports category. Just kidding, it's Lifestyle. They missed their chance on that one. And Poop the World? Entertainment. They shoulda gone for Travel. By the way, if you like lists, then also check out the 10 most expensive apps on the Silicon Alley Insider, ranging from $179 to $899. Seriously.
