In haste...
I've explained on Wikipedia how I regard the difference between a dictionary and an encyclopedia is, and that there is good reason, not founded merely in paper, for the distinction. Mere assertions to the contrary are not persuasive.
However, I do think that it's an interesting idea to find some *consistent* way to mark all mere dictionary-type entries in Wikipedia. I think that could be a good way to solve the problem I raised on Wikipedia about the difference between an encyclopedia and a dictionary.
Obviously, as I said, I can't be responsible for this project. :-) If it happens, unless Jimbo specifically asks me to do it, I won't be the one to make the executive decisions.
