This is partly because (in stark contrast to Japanese), Korean has one of the most perfect writing systems ever, so it's very easy to learn.
It is fairly unfortunate, although strictly speaking, it's not an alphabet at all. And no alphabets are phonetic (apart form the International Phonetic Alphabet, used for scientific purposes), as alphabets represent the distinctive units of speech, rather than the actual sounds that are produced. Although as any writer of English will know, in many alphabets, this representation is far from exact.
Done. Although I hadn't noticed until you pointed it out, thanks to my chunking strategy.
