You have now: I like it. And in fact I think the community of
developers that likes it is larger than you imagine, because Qt
replicates the syntax for not just I/O but putting stuff in containers
too.

The reason people go for printf instead of iostreams is that format
strings are a lot easier to use when you need to do formatting,
because the STL's formatting tools are blah. On the other hand,
iostreams don't corrupt memory if you make a mistake in labeling a
data type.
