"Growing Wikipedia Revises its "Anyone Can Edit" Policy"

In Katie Hafner's "Growing Wikipedia Revises its "anyone can edit" Policy" she writes of how Wikipedia advertises and attracts many people to the site because anyone can edit the entries on the website but they have changed things up so that some posts cannot be edited at all and some may take 4 days after registering to be able to edit them. She states "Wikipedia is the online encyclopedia that "anyone can edit". Unless you want to edit entries on Albert Einstein, human rights in China or Christina Aguilera.". Wikipedia has become very successful mainly because after a post is first made available it becomes more and more accurate as time progresses because more and more people stop by the post and edit it until there is nothing else to add and the post rivals any other encyclopedia. The site is not simply a collaboration of many peoples ideas, it is checked and edited constantly by a small group of individuals for accuracy and to keep tabs on slander and such that may be posted, this group of individuals may also see it fit to make some posts un editable due to constant changing by people for one reason or another.
After reading this essay I realized that I agree with Wikipedia on their policy on making some posts impossible or difficult to edit. It seems very appropriate that some posts that are hot topics or that are very controversial should be difficult to edit because otherwise people will ruin the posts and type very inappropriate things in the entry that some may find offensive. Overall I think that Wikipedia is a great thing and it is a true wealth of information but for the reasons discussed earlier I do not think this encyclopedia should be used for school research for there is a small chance that the information could be highly biased or just plain incorrect.
