Stupid Web Tricks
Oh, boy. Check out this link.
No, I've not all of a sudden gotten a job at Dell. This is an example of really bad site design. Check out the URL: it has the text string to be used within it. (Where it says: "MSG=we+are+on+the+phone"...) Whatever's in that string appears as the message on the page. Which means you can make your own Dell webpage saying that its European operation is on the phone to George W. Bush. You could get it to say whatever you want, really. Want Dell to come out against the War on Iraq? Write in a political message of your choice, send the link around to all your friends, and watch a net rumour start.
OK, assuming you have nothing better to do with your time...
(link from NTK, sort of. They had Dell phoning Anne Widdicombe.)
