Hangul in Indonesia

I was at Tom N Tom's today, perusing Asiana's in-flight magazine, and learned that a small Indonesia tribe in the city of Bau-Bau (Bauer-Bauer) have adopted hangul as their written alphabet. Though the tribe has their own oral language called Cia-Cia, they have not been successful in maintaing an official system of writing. The Yonhap News Agency has more on this news story.

Though I still have issues with its patchims and some vowel sounds, I do have to admit that hangul is quite a nifty little alphabet. I think it's definitely better than the English alphabet. Come on now. Is it really necessay to have a 'c', 'k', AND 'q'?
