What i found interesting is the comparison between the "newer" 
languages and D ( see the reddit thread ).

9   Go      4.1022
15  Kotlin  1.2798
18  Rust    0.7317
35  Julia   0.0900
46  Vala    0.0665
50  Crystal 0.0498
53  D       0.047%

While i can understand Rust ( Mozilla ), Kotlin ( Jetbrain ), Go 
( Google ).
Even Vala and Crystal are ranked higher then D.
