One thing it's lacking is actual demand/supply values. Here in the UK the demand for Linux skills is quite high. The banks, stock exchanges, hedge fund and the range of online business and startups out there are increasingly Linux based and all competing for skills. At the same time, tighter immigration laws in the UK make it harder to get skills from abroad. The result is that it's good to be an EU citizen looking for a Linux job in the UK at the moment. I think a similar problem would be skewing the Java skills demand level on Linux. A lot of applications out there are Java based, and a lot of it's done on Linux. But like for Java, the requirement is often not for a very high level of skill on Linux systems running Java applications.
