A while back we had a poll question that asked people which dictionary they used most frequently. The problem was that it was Chinese-centric (this was before we had many Japanese learners on the site) and the largest response category was "Other," which wasn't terribly illuminating.
So, we know that people on Skritter like using MDBG and Nciku (and to a much lesser extent Zhongwen.com), but we were wondering what other dictionaries you guys typically use, and why?
Personally I've been a fan of MDBG for a while, but because I'm learning Chinese I have no sense of the relative merits of Japanese dictionaries or non-MDBG/Nciku Chinese dictionaries!
