Only eight serious errors, such as misinterpretations of important concepts, were detected in the pairs of articles reviewed, four from each encyclopaedia. But reviewers also found many factual errors, omissions or misleading statements: 162 and 123 in Wikipedia and Britannica, respectively.

As well as comparing the two encyclopaedias, Nature surveyed more than 1,000 Nature authors and found that although more than 70% had heard of Wikipedia and 17% of those consulted it on a weekly basis, less than 10% help to update it.

Teachers spend most of their working lives out of sight of other adults. If they are to successfully incorporate a new and complex resource like computer software into their teaching practice, they must have access to other people from whom they can learn, either experts who have already mastered the resource or a community of teacher-learners who pool their efforts and share their exploratory findings. Thus, it is not surprising that we would find that exemplary computer-using teachers are more likely than other computer users to be working in a school with many other computer-using teachers. It is also true that exemplary teachers may themselves create (rather than just be created by) an environment in which many teachers use computers. Nevertheless, it is instructive that of the 51 separate teacher environment variables examined, the one with the largest difference between exemplary and other computer-using teachers was simply the total number of teachers at their school who used computers.

Plazes wird aber erst dann nützlich, wenn genügend Bekannte auch dabei sind (Ein Fall von Metcalfes Law (Biblionetz:w00861) Zudem ist der Client derzeit noch nicht sehr benutzungsfreundlich.
