Learning is important. Part of being a developer is that you must keep learning new techniques and facts that help you accomplish your goals or your clients goals. So I'm not saying we don't need to deal with internationalization, localization, and globalization. When the time comes, deal with it. I'm just saying there's no shame in being a developer with little or no expertise in those subjects. Many commenters here don't seem to acknowledge the many amazing technical things that developers generally do know about.

Thanks for taking the time to respond in words.
