Wheel 'O Yum Voting
Voting Basics
The Wheel 'O Yum allows each member of a wheel to vote on the restaurants.
There is no limit on the number of votes; each member can vote on every
restaurant if he/she chooses to.
The possible vote options range from strong opposition (-2) to strong
preference (+2). Negative values indicate opposition or dislike to a
restaurant, while votes greater than zero indicate preference to a
restaurant.
A vote of zero (0) indicates an indifference to a restaurant. Voting
a zero for a restaurant is like saying, "I don't care" for that
restaurant.
How the Restaurants Get Their Slice
To determine the size of each restaurant's slice on the wheel, the
Wheel 'O Yum averages the vote from all members present at the wheel
for each restaurant.
Restaurants with a negative average vote are removed from the wheel.
The remaining restaurants are allotted a slice on the wheel. The size of
each restaurant's wheel is proportional to its average vote in relation
to the other restaurants' slices.
Voting Rational
Mathematically speaking, zero (0) typically represents non-existence or
void. As such, you may expect that restaurants with a vote of zero (0)
are omitted.
The Wheel 'O Yum interprets a vote of zero (0) to represent
indifference. That is, it's neither preferred nor disfavored. Part of
the reason for this is to satisfy the vacuous case.
If the votes are reset (such that all restaurants have a vote of zero
(0), the resulting wheel will allocate an even slice for all
restaurants. An argument can certainly be made that this should be the
case only when a restaurant has a positive (preferred) vote.
By voting positively for a restaurant, it signifies your preference for
it. Likewise in reverse--voting negatively signifies your dislike.
Voting a zero signifies you neither prefer nor oppose it--you're
indifferent. Voting a zero is equivalent to saying, "I don't care"
for that particular restaurant.
To constrain the outcome to a particular set of restaurants, vote
negatively for all the restaurants you want excluded.
When rendering, the wheel averages the votes from all users and omits
all restaurants with a negative value. The remaining restaurants are
allotted a slice; the size of which is proportional to their respective
average vote.
Future
One of the near-future versions of the Wheel 'O Yum may simplify the
voting slightly by removing the numerical options (+2 -> -2). In its
place will probably be something to the effect of "Yes", "Don't Care",
and "No".
