Julia is getting plenty of attention. It's pretty obvious at this point that Julia is destined to eventually be a major player in some fields.
The main problem facing the language is maturity. That will come with time. Until it has fully stabilised, has a mature runtime, has a mature library ecosystem, and has strong debug and post-mortem tooling, it is not something everyone should use.
They're smart alright, but I think Julia has gotten a lot of play on other channels besides the Matlab/tech world. The stopper is for me is use cases. I play with ideas in Mathematica (notebook IDE for decades) because it has everything at my fingertips, keep J programming language opened on my desktop for quick prototypes (not just as a desk calculator), and if I need technical libraries and speed, I just use C with the relative libraries (even though I should learn Fortran :) ) I like Julia's syntax, and I think it will be more general purpose as it matures, but it is already the wild mistress of the Matlab playboy.
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 ;)
Juila is one of those great things that everyone should use, but are simply bot promoted enough.
