"Popularity in this case is measured by queries related to programming languages that have been aggregated from 25 different search engines."
That seems a very odd an inaccurate way to make an assessment. Those measures may work for 'who's the favourite love islander?' (Or some other media twaddling nonsense) but not for a skill set millions of people earn a living from.
If I were (am) cynical I'd say the software company just wants some publicity from this.
