Oh dear - Wikipedia
A colleague just sent this through to me. He was doing so research using wikipedia for science and scientists.

The entry has been edited with rather juvenile additions. This is disappointing as we don’t need this sort of vandalism.
However, as a teaching opportunity this is useful, it does highlight the risks of a trust based model of knowledge creation, the issues of peer moderation and the amount of time it takes for the moderation team to check and moderate.

This is one of the risks we have to accept with a brilliant and powerful resource like wikipedia. We as I have blogged before must teacher our students to validate all information sources, be they wikipedia or the Encyclopedia Britannica.
