This question on Programmers' has converted to CW.
However, the question itself hasn't been edited - not even by the OP, and there are only 16 answers (at the time of this posting).
So why, or indeed how, has it converted to CW?
The only thing I can think of is that the number of answers threshold has been reduced from 30 to 15 (?).
Is this a network wide change or can it be altered on a site by site basis?
