most teachers do advise the students that Wiki is an uncontrolled source.

One advantage of such a source is that it is not under the control of someone with an agenda who will present the information in a way that fits his agenda. You can add an alternative point to any article, as Bob mentioned in his his original post.

The law of large numbers says that the larger the sample, the closer the average is to reality. If your performance appraisal at work is dished out by one person, it may mean that you are a bad employee.. but it may also mean that the boss doesn't like you.

If your appraisal is handled by a team and ALL of them give you a bad review, it narrows down the source of the problem quite a bit.

It's statistically less likely that EVERYONE will be wrong at the same time.. but even if they are, Wiki gives the lone ranger an opportunity to add the missing piece of information that may set the record straight. If nothing else it is an exercise in viewing a picture that is larger than your own world view.
