The Denver Post got 5 experts to evaluate articles in their areas of expertise.
The results? Four out of five agreed their relevant Wikipedia entries are accurate, informative, comprehensive and a great resource for students or the merely curious.http://www.denverpost.com/entertainment/ci_5786064
The fifth scholar called his chosen entry "not very good," found some details to be inaccurate by omission, and said similar entries in more accepted encyclopedias like Encarta do their job better.
