Sure, I get it, and I appreciate that.  The point was that you can't 
change things, even for the better, without *advance* notice to the 
people who are going to have to scramble to fix things on an emergency 
basis when you don't warn them.

Yes, you did, but there was no warning ahead of time.  I agree that the 
30 day window, after the change, was a large mitigating factor for that 
change.  But still...  Changes without warning really bug the heck out 
of anal retentive change control (read large enterprise) folks.  And me 
too, can you tell?  :-)

Thank you, that will be *very* helpful!  I'll shut up about this now, I 
think we've beaten it enough on-list.

FWIW, I agree, and I do monitor them.  I will note that most if not all 
of us have *lots* of similar feeds to keep track of though.  To mangle 
the quote, please "Inform early and often."

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
