Since computation of up/down votes is now available to

everythingians, it is also possible to compute the

*controversy index* of a

writeup as follows:

`
`

`
CI=1 - (abs(U-D)/abs(u+D)) if U or D are not both zero
CI=0 if U=D=0
U is the number of Upvotes
D is the number of Downvotes
`

`
`
A highly controversial (divisive) writeup would have
U=D, with CI=1, while a node with U or D equaling zero (unanimity) would have a CI of zero; anything else would fall in between.
