Hey Stephen,

This is a extremely well written and reasoned post and I can't help
but I agree with every point you made.

In my previous position, I worked in the firm's infrastructure group,
where we 
wrote and maintained libraries that were the "standard library" of the 
firm on which other apps/libraries were built.  Given the size of the
user 
base (in the thousands), it is simply unthinkable to rebuild the world
because 
of a new release of boost.  The current version is 1.33.1 and that's 
unlikely to change for a while.  Finding debilitating bugs/changes in 
a new release makes people even less likely to want to move.  This is 
bad for boost, too, as you lose not only direct boost users/testers, 
but also the feedback that developers send back to their
compiler/standard 
library vendors.

Nor should it make one forget that even though grateful for your
efforts,
there's only as much pain as people are willing to go through.
