My wife is Korean, so I'm exposed to all kinds of interesting culture differences between America and Korea. I'd like to share a few of those culture differences so that people can learn more about Korean culture. I also want to show people that a lot of things we take for granted as just "how things are done" are actually nothing more than cultural norms that can and do vary from place to place.
Amazon identifies every product for sale with a ten-digit alphanumeric code called an ASIN (Amazon Standard Identification Number). Whenever you visit a product page on Amazon, these number is somewhere in the URL; however, it's not always in the same place in the URL. This makes it a little bit hard to pull the ASIN out of an arbitrary URL.
