Linux has become too big
Linux has become too big. If he were amongst coders only, this wouldn't even be an issue. I'm used to language far worse than that. It's not a problem when you know that those people don't mean you any harm. It's even funny quite often.
I haven't met that many 'faint-hearted' programmers. I wouldn't know even one who would get aggressive, if you insulted his mother. They can see the wink in there. That's how it should be.
But ... this is different now. Linux has grown. You have to deal with 'certain polished personalities' now. Good luck Linus!
