Wikipedia. Great site, but why does Wikipedia allow anyone to "edit"?

Question

For example: I was interested in finding out the income per capita of Singapore. It turned out to be, according to what it says on a list they have of about 118 countries, that this tiny, little 'protectorate', or country if you will, Luxemburg, has the highest per capita income. Are you ready? Better sit down. $69,800.Vs. approximately $41,500 in the US. This amounts to $33.50/hour for them and $19.80/hour for us here in the USA. Now i would like to assume that this info is nothing but fact, but if anyone can 'edit' does it still remain true ? please answer ASAP if at all possible. :- >

Yeah, thank you, i though there must be some kind of oversee.

Answer 1

The point of the word 'wiki' is that it is information gathered from, and managed by, everyone and anyone.

You pays your money and takes your chances, and most of the time it's okay because if it is incorrectly updated, someone else is likely to come along and fix it before too long.

I love Wikipedia, frankly.

Answer 2

its free and anyone can add their own knowledge, im pretty sure there are people that look at the additions to make sure they are accurate
