Choices.html, first bullet argues that boost::format("...") % expr1 % expr2
is way cooler than boost::sprintf("...", expr1, expr2).

I don't really have a problem with the % syntax (except for the operator
precedence, perhaps) but choices.html doesn't do a very good job of
explaining its benefits.

One non-obvious advantage of the sprintf-like syntax (the obvious advantage
is of course sprintf "compatibility") is that sprintf() can detect arity
errors.

I think that both forms can be useful depending on the context, so both
should be provided.

Also, I think that the str() free function should be named to_string.
