Online Dictionary

If you are looking for an easy to use online dictionary you might want to check out DictionaryOfDefinitions.com. It seems to be a very easy to use simple online dictionary. They are still in the redesigning phase but I think the overall tool is very useful.
The only thing I don't understand is what they mean by elegant. The title header says Dictionary of Definitions - simple- complete- elegant. I am not sure elegant would describe this site but the dictionary itself is useful.
