Subject Re: 6 months a more realistic release cycle?
Date Fri, 20 Apr 2012 18:33:56 GMT

is there any stats on customer adoption of new versions? I'd wonder if 
people generally move to new versions every 4 months, as that could be 
potentially painful for them as well. Given the amount of questions 
regarding older versions still percolating, i'd guess the answer is 
they'd be ok with it too.
