Having seen banking stacks, I'm inclined to believe TIOBE.
Most programming is not the kind programming you see talked about on HN. VB is still huge in legacy stacks.
right, but how much of that code is using a version of the language that hasn't been supported for 15 years? according to tiobe the answer is more than the amount of bash,powershell, and perl put together (and the amount is dramatically increasing)
