I am not sure what the article tells: that Julia is now popular 
and people use it? Or that D (and other languages) need to 
compete against self-written PR articles?

(Many system-programming languages can achieve the same 
performance as what the article describes, when several research 
institutes combine forces on just that.)

But yes, Julia's focus on small niche, and its popularity in that 
niche makes it attractive for contributors.
