The Science magazine Nature has recently published a study in which the accuracy of the Britannica was compared with that of the Wikipedia in the realm of Science articles.

The Britannica had 3 errors or inaccuracies per article, Wikipedia had 4.

So, WP is quite reliable in the world of science. That fits with my impression too and I do not at all agree with those who say that WP cannot be relied upon. It depends on the context. WP is quite good in reporting in the factual fields. I find it reliable in sports too and many other fields. But when it comes to fields in which emotions and prejudices play a role you should not trust the contributors.
