Part of being able to thrive in a connected world is observing what might be called "digital etiquette" - and it's tough, because this etiquette is poorly defined, not at all explicit, and always changing. Something that would be a part of any digital etiquette is image resizing: that is, one should resize images depending on both their intended use and the vector of communication. For example, a cute pic of your dog napping sent via email to all your friends should NOT be a 9MB photo so large that the dog's nose takes up your whole screen - it should be something like 800x600 pixels, which will result in an email-friendly sub-100kB file. Anyway, I'm happy to see (thanks to Lifehacker reader OS's comment on this Lifehacker post) that image-resizing has been built into the iPhone's interface when sending photos. It uses qualitative size descriptions (Small, Medium, Actual Size), but quantitative file data sizes - which likely reflects AT&T's switch to limited data plans. Let's hope this new feature gets used, and teaches the users some digital etiquette in the process!
