These show broadly that Java is the most popular and now rising in popularity, because of Android phones I'm guessing, Objective-C is climbing massively thanks to the iPhone and iPad. On Tiobe, C, Objective-C, C++ and C#'s popularity at positions 2-5 between them add up to over 42% of all the programming languages. Makes you think!
An interesting quirk. On the Google trends link above, the country with the most search volume (per head?) for C++ and C# interest is Ethiopia, surpassing even India! C++ seems to be taking off in Addis Abeba!
