You might call it self-written PR articles, or educate yourself 
who is using it.

Also I did mention C++, which you glossed over on your eagerness 
to devalue Julia's market domain versus D among HPC communities.

As someone that spent two years at ATLAS TDAQ HLT, I know which 
languages those folks would be adopting, but hey it is a piece of 
self-written PR.
