Google has already made some effort to publicize hangul to the world, including its use on Google's main search page on Hangul Day, a national holiday here in Korea, as shown in this 2011 post. However, it can and should do much more, for several reasons.
Some years ago, a poll of academic experts on Korean culture published in the magazine Koreana showed that hangul was considered to be Korea's greatest cultural achievement. A similar poll of the Korean people would no doubt produce similar results, as hangul is widely considered to be this nation's crowning cultural achievement.
Moreover, as I noted in a 2009 post, hangul has the following characteristics (I've updated the list slightly here to account for recent developments).
- Because it is so scientific and phonetic, it was an important factor in accelerating the uptake of computers, mobile phones and all sorts of digital electronic devices here.
- It is possible to type much faster on a hangeul computer keyboard than on a qwerty English keyboard--much faster! This principle applies to smartphones and tablets as well.
- Because Hangeul is alphabetic, it was conducive to the rapid development and growth of the graphics industry, which began back in the 1980's. Some of us remember when there were no Korean fonts, only hand calligraphy.
- Literacy is an essential requirement for the information society and Hangeul helped promote it in Korea. For years now, South Korea has had near-universal literacy.
