I meant that as a PL being pitched as a Matlab replacement, and for math and science communities, it has had some highly visible, hyperbolic articles in Wired ("Man Creates One Programming Language to Rule Them All"), Venture Beat, Fast Company and other more broad startup and popular tech magazines. I like the programming language J, and I think I can truly say it doesn't get a lot of exposure outside of its niche along these lines, so I wouldn't say Julia doesn't have good marketing; J has yet to be featured in Wired ;)
