Interesting post on average developer salaries by programming language, it was worth noting how the data was refined and also that very little or no appreciation was given for geographic location, that said, this is an interesting slice of data (image from the blog of Ben Podgursky).

My assumption would have been that the mobile based languages (Objective-C) would have been at the top as well as enterprise focused languages like Java. I am going to be honest I do not understand how ActionScript (superset of ECMAScript) sits in the premier position, I am assuming that there are a lot of well paid Flash developers who are still making a ton of money on a dying platform.
