Are you implying 3♦ is a cue? Anyway, I usually don't reply to rudeness, but since I think I have known you from BBO forums (MrAce?) I will just make this comment and be done.
Perhaps all partner is interested in is hearing about a diamond singleton/control and the best way to find that out is by bidding 4♣. Anything else and you might land in a position where you have no clue about that.
