To be fair to NIST, there really aren't many people using WWVB as a 
source of laboratory-grade timing signals.  As others have pointed 
out, it isn't accurate enough for true time nut performance, and to 
get all of what it *is* capable of requires heroic efforts.  So in 
truth, the real market for WWVB is not time nuts -- it is people who 
want to know the time of day to within a second (the "atomic" clock 
crowd).  And there are LOTS of them.  So the change is likely to 
provide a modest upgrade path for the vast majority of actual users, 
at the expense of a few die-hards (hobbyists, mostly) who are trying 
to get more out of an LF timing source than it is really capable of 
delivering.

 From a public policy standpoint it seems to make good sense, however 
much it may offend time nuts' sensibilities.

Best regards,

Charles
