It's true (and it's great news) that Python is becoming one of the most important and popular programming languages, but this article does a pretty poor job at showing this and explaining why.
Other than Python's popularity for web development (where it faces competition from Ruby and PHP) Python has been adopted in many other settings, and that probably contributed quite a lot to the numbers indexed. For example, in the last year many of the biggest financial institutions have moved to developing critical parts of their systems in Python. In fact, it can probably be said that Python became popular _despite_ not becoming very popular for web development until quite late in the game.
