* Abstract: Wikipedia's brilliance and curse is that any user
can edit any of the encyclopedia entries. We introduce the
notion of the impact of an edit, measured by the number of
times the edited version is viewed. Using several datasets,
including recent logs of all article views, we show that an
overwhelming majority of the viewed words were written by
frequent editors and that this majority is increasing.
Similarly, using the same impact measure, we show that the
probability of a typical article view being damaged is small
but increasing, and we present empirically grounded classes
of damage. Finally, we make policy recommendations for
Wikipedia and other wikis in light of these findings.
Really interesting metrics for measuring the actual impact of errors in WikiPedia!
