wow!!! My 2nd choice of online korean dict daum dict!!!
GREAT!!!!
I have tried to compare Daum dict and Naver one before....
Naver one has a 유의어/반의어 feature that I like, while for Daum, the pronounciation can be downloaded
anyway, so well done, Ryan~~

Have you ever really looked deeply at a dictionary entry? I've been researching the underlying structure that goes into creating dictionaries. xm-l and API calls to Merriam-Webster. Fun for me the programmer.

WordNet dictionary is cool.

The Tuttle Dictionary deals with most of the issues I have had with dictionaries (see below). It has about 5000 words, in large type, laid out to be easily read in blue and black ink. It has romanization.
Dictionaries have been difficult for me to use with Korean.
First, Hangul.
Second, sort order.
Third, need sample sentences to understand in context.
Fourth, part of speech not listed in every dictionary.
Fifth, English loan words that are just spelled weird in Korean.
Sixth, Chinese words (Hanja).
Seventh, particles and grammar that I don't understand. what they are doing (switching verb to adjective? or is it adjective to noun? or conjugating to some tense?)
Eighth, synonyms, antonyms, collocations, and idioms.

Korean/English dictionary. Large photos or full color illustrations grouped by topic. Would word well in a classroom setting to teach vocabulary, 4000 words. Sentences. Index easy for a native English person to use (also has Korean alphabetized index)
Dictionary is English-centric. It wasn't as useful to me when I first started learning, but now that I know a bit more and am in a vocabulary building stage, I can see referring to it as helpful to reinforce words I have seen other places. Very visually orientated.

There is a bilingual edition of the Oxford Picture Dictionary for Korean.
