What programming language should you learn?

Check out the most popular programming languages in an easy to use visualization. Click on the graph to change it from weightings based off Google Code Submissions, Yahoo Search Results, and many more. Data and description courtesy langpop. The visualization is a TreeMap written in processing.js using code by Felix Menard. Clearly the big winners here are the C based languages: C, C++, and Java. Java is a clear winner when looking at books printed by Powell books. However web based technologies such as PHP and SQL blow out the competition when it comes to Craigslist job posts.
