Speaking only for myself -- I wouldn't use a logging library that didn't 
support << operators.

For years now I've been in the habit of defining a custom << operator 
for each important class in my applications. Then I can debug by writing 
such an object to std::cout -- or to a log file. Or, using 
std::ostringstream, I can convert to a string representation if I have 
something more exotic in mind (e.g. output to a debug pane in a GUI).

My point is that this single operator<< method suffices for all present 
cases in which I want to display my new object. Even if a printf-style 
logging library is extensible using some different mechanism -- why 
should I bother? I'd just pick a library (or write my own) based on << 
instead.
