Why it "works" Network Effect Wikipedia benefits tremendously from the network effect. The network effect is when a user of a product benefits more from a product if other people also use the product. Telephones are a textbook example. If only a few dozen consumers have telephones, then the telephones aren't very useful. But if millions of consumers have telephones, they become more useful since each telephone owner can contact many people. The large number of Wikipedia users benefits Wikipedia. First, the more editors there are, the the higher the accuracy and quality of the articles. Secondly, it gives an incentive to users to edit. Since editors know the each article will be read by thousands of users, the sheer influence of each article is a strong enough incentive to edit, even though Wikipedia is free.

In addition, editors are anonymous and may have a conflict of interest, or might have inadequate knowledge of the article's subject. Yet, because Wikipedia is open to any edits, it is also likely to be corrected. It operates by a system of checks and balances from many editors.

To prevent bias and to protect the encyclopedic quality of its articles, all edits on Wikipedia must in theory be a verifiable fact. Moreover, it must have a reliable source to verify each fact. 2. No Original Research. As an encyclopedia, it is mean to be a secondary source of infor
