API folks, could you please, please NOT return 401 "Not authorized" when an authenticated call with a perfectly valid username and password requests a /queryusername.json where that queryusername happens to be a username that does not exist.
Rather return 404. By returning 401 you are making it impossible for me to tell where the actual problem lies and inform the user. Is it with the user's password, or is it because the user wanted information about a Twitter account that does not exist? Dewald
