That was just an example in my post. I used to do a lot of C programming in my spare time. My commonly used tools back then included splint, valgrind, gdb and man. Like I said, developers will find similar tools when the language they are coding in changes.
They don't care about Vim and Emacs, they are not Python devs and they don't live in SF (talking about the other 90% of devs naturally).
