I've seen a lot of marketing ploys, but this one takes the cake. At the risk of overanalyzing, let me point out that this advertisement for Internet Explorer 8 reads so much like spam that I almost closed the window without reading it. What stopped me? The fact that it looked so much like an entertaining bit of spam. And so I read on, as Microsoft hoped I would. Will I stop using Firefox in order to search for the $10,000? No, but kudos to Microsoft for the effort.
