• The beauty of open-source applications is that they are continually improved and updated by those who use them and care about them. Dartmouth researchers looked at the online encyclopedia Wikipedia to determine if the anonymous, infrequent contributors, the Good Samaritans, are as reliable as the people who update constantly and have a reputation to maintain.
• By subdividing their analysis by registered versus anonymous contributors, the researchers found that among those who contribute often, registered users are more reliable. And they discovered that among those who contribute only a little, the anonymous users are more reliable. The researchers were most surprised to find that the reliability of Good Samaritans' contributions were at least as high as that of the more reputable registered users' contributions.
