With all the news about wikipedia lately, you would think that the onlin, free, collaborative encyclopedia was nothing more than a cess pool of inaccurate, messy, worthless information (that creed is actually what uncyclopedia is shooting for, and doing a very good job of it, if I may say so myself).
But this article suggests that the difference between Wikipedia and the Encyclopedia Britanica is not that far. Errors are found in both encyclopedias, although wiki did have a slightly higher rate.
Interesting read.
