wow, thats a list
great job Perry
but you havent voted yourself ?
(I seem to have been the first..)
I use Dictionary.com when
I look up a word (=not often - cause I a lazy beggar as opposed to haveing a huge vocabulary
It uses/quotes a bunch of other online dictionaries.
I've been so happy with it I've never bothered trying anything else
I voted "other" also because I mainly use German-English-German dictionaries.
These days I use dict.cc
Housetier recommended it here somewhere (I've wanted to make a post about it because they have a wonderful vocabulary "box" - as you look up words you can add them to the box and learn them. This might prompt me..)
I used to use Leo
which is also very good
