If v is the average number of votes per user allocated per day, u is the average number of users on E2 per day, w is the average number of writeups added per day, du is the average likelihood that a node will be upvoted by a user, dv is the average likelihood that a node will be downvoted by a user then the vote death of everything will occur in:
    ( v . u . w - 2 ) / ( du . dv ) days

If vote death is equivalent to all writeups possessing a reputation less than or equal to -2. I suggest the construction of vast generation ship to carry us to other, hypothetical, interactive, associative databases so that our great civilisation can be preserved.
