Techniques for statistically estimating a rating or other "figure of
merit" for a user are disclosed. According to one such technique, a first
quantity of submissions that were submitted by a user is determined. A
second quantity of submissions that (a) were submitted by the user and
(b) obtained a particular rating from a rating mechanism also is
determined. A user rating for the user is determined based at least in
part on the first quantity, the second quantity, and a factor that is
independent of both the first quantity and the second quantity--such as
the probability that an answer submitted by any answerer in a population
will obtain the particular rating from the rating mechanism. The
influence that the second quantity has on the user rating relative to the
influence that the factor has on the user rating may depend at least in
part on the first quantity.
