Loved this post by Seth Godin. More people need to read this:
Next time you get an email (copied to all your friends plus people you don’t know) warning you about some horrible computer virus, some sick kid collecting greeting cards or the National Do Not Call List, don’t just blindly follow instructions and then forward to everyone you know.
Instead, go to Google and type in the word “snopes” followed by the gist of the cause or the event or emergency. Snopes will then tell you whether it’s a hoax or not. Save you and your list a whole lot of time.
I know most of the people I associate with aren’t as web savvy as I may be, but forwarding unsubstantiated emails has nothing to do with experience on the web: it has everything to do with being too lazy to do some basic research. There is no excuse for it.
