Cool, it would be a cool statistic also, the user who used the largest number of different languages in problems and got AC with them. the user with the less number of non-accepted submissions would be cool too.

Mr. Ahmed Aly, could you publish a list of top 3 (or 5) for each category? I'd love to see how close other contestants are from first place.
