  Several hundred Wikipedia articles are deleted every day because they lack
sufficient significance to be included in the encyclopedia. We collect a
dataset of deleted articles and analyze them to determine whether or not the
deletions were justified. We find evidence to support the hypothesis that many
deletions are carried out correctly, but also find that a large number were
done very quickly. Based on our conclusions, we make some recommendations to
reduce the number of non-significant pages and simultaneously improve retention
of new editors.
