Surprisingly, Wikipedia is only fourteen years old. Wikipedia encounters a great challenge. While new editors are not welcome, the number of editors is in decline. It is only 18% of the editors who represent the new comers. In order for Wikipedia to survive, more new comers should be accepted. There is a tendency of the older editors to delete articles posted by newer ones. In my opinion, the greatest challenge of Wikipedia is not new technology such as smartphones, but the way new editors are treated. Wikipedia has a greater chance to survive if new editors are encouraged to post instead of having their postings erased.
