Snopes
If I had a dime for every email I’ve been forwarded about some missing girl, chocolate chip cookie recipe, or Nigerian bank deal…It’s too bad that the people who would really benefit from knowing about Snopes seem to be unaware of its existence. If they were, there might be less junk in my inbox everyday. I’ve responded to these folks with links to the pages describing the hoax, but rarely with any effect.
Regardless, Snopes offers a vital service to the internet community (or at least those willing to take advantage of it).
