Always wanted to be able to sit down and read the newspaper. I've got maybe 200 kanji I'd remember pretty quick and another 300 that would take a little more reminding. Then only another 1500 to go to read at a junior high level! Wish I had your facility for languages, D.
Learning Kanji has nothing to do with facility for languages. When I was living in Korea I studied Kanji for fun (they still teach it for historical reasons in Korean schools, though the Koreans were smart enough to come up with an excellent alphabet which has almost entirely displaced Kanji apart from the odd character in a newspaper). Learning Kanji is basically memorisation and constant practise, nothing to do (at least in my experience with language facility). I have a friend in Japan who speaks excellent Japanese but his writing and reading skills are poor; Kanji are just pictograms, they have nothing to do with language itself. I think if Japanese had a proper alphabet, excellent speaking skills would be more readily transferable to writing and reading skills. The same applies to Chinese. Actually, I have a girl (Chinese) on my MSc who admits that the Chinese system is totally inefficient but culture is neither logical nor efficient, it simply is what it is. In the 18th century there were many (failed) attempts to reform English orthography but we are stuck with the horrible spelling system we have today and it is very, very unlikely to change. OK, that was a tangent. Final point, learning Kanji has nothing to do with ability to learn a language.
