 Yeah, they're totally opposed to having equal-length seconds, and they
 really showing the world with this demonstration, aren't they ?
 
 I have heard a fair bit in private communications about why and how
 google did implement the leap-smear, and let me assure you that
 they have a special place in Googles hell reserved for those who
 prevented leapseconds from having a quick and swift death back when
 that was first proposed.
 
 I probably missed discussion of this survey a couple years ago.

Not as much as there should have been.  Thanks for reintroducing it into the 
mix.

 I note two individuals at Google replied. One answered  I am not satisfied 
 and prefer UTC redefined without leap of second, and one I am satisfied 
 with the current definition of UTC which includes leap second.
 
 Maybe there's not really a consensus within Google either?

Regarding Google Hell, this has a particular meaning:

None of our factions has ever been particularly concerned about query 
placement, and in general the various resources are easy enough to find.  One 
might, however, point out that the Google Blog itself doesn't show up until the 
third page of results ;-)

If anything has prevented leap seconds from death it is the weakness of the 
proposal itself.  And the real-world distinction between Universal Time and 
Atomic Time; Death to leap seconds! is the rallying cry of somebody who wants 
to pretend that two distinct concepts are the same thing.

Regarding private communications, the most obvious thing about this mailing 
list is the dearth of participation from supporters of the death penalty.  
Rather than anecdotes in private email, such individuals are encouraged to 
participate here.  Or perhaps as the EOC questionnaire shows, there are simply 
many more supporters of the status quo:

The plural of anecdote is not data.

It is more of a 'Atomic Time is a completely adequate basis for civil time' by 
rejecting the notion that exact alignment to snyodic day is a requirement. 
Apart from some naming sophistry, that's the root of all the discussions and 
disagreements here.
