Sobotka: Why GIMP is inadequate

It is hard to get reliable data on language popularity. That said, a search for "int main" lang:c vs lang:c++ on code.google.com shows C and C++ nearly tied. I think it is safe to say that a few years ago C++ would not have been anywhere close. (Caveat: it is naive to assume that a lot of care and attention goes into ensuring accurate search stats in a search engine.)

As far as freshmeat goes, it would be nice to know the relative popularity of C vs C++ for active and new projects versus inactive and old projects.
