I'm giving a talk in April 2011 on "Developer English" and showing my non-developer audience, mostly English teachers, various diagrams to explain how developers see their industry etc.

One of these diagrams is "Hot Technologies", basically, if you want to become a developer, what technologies should you learn to have the highest chance of (1) getting a job (2) making a good salary, and (3) work with the most exciting technology.

This is a draft I made just to get some ideas out, basically C#, PHP, Java are where the bulk of the jobs are. Mobile development has a big future. JavaScript is becoming more and more important, and I want to list "minor technologies" such a Python, Ruby on Rails to the side, I assume e.g. that in general, there are a much smaller percentage of jobs in these technologies as in C#, PHP, Java.

How could this diagram be improved?

UPDATE

Thanks everyone for your suggestions. I included most of them in my updated graphic. Does anyone know of more Java technologies that would be appropriate here and could anything be added to the gaming technologies?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
