I don't write modern C for daily use, so I can't really say. But I've been re-learning and writing C99 more these days, not professionally but personal use - and I appreciate the smallness of the language. Might even say C peaked at C99. I mean, I'd be crazy to say that C-like languages after C99, like Java, PHP, etc., are all misguided for how unnecessarily big and complex they are. It might be that I'm becoming more like a caveman programmer as I get older, I prefer dumb primitive tools.
C11 adds a couple of nice things like static asserts which I use sometimes to document assumptions I make.
They did add some optional sections like bounds checking that seem to have flopped, partly for being optional, partly for being half-baked. Having optional sections in general seems like a bad idea.
