Pretty funny. Always interesting to see views about this stuff from people who aren't in the internet marketing world. Funny to see that the author was actually afraid to click on one of those ads for fear of getting a virus or having his identity stolen. Also interesting to note was his opinion that these ads usually look like "obvious scams."
They forgot to mention however, that the main reason why so many marketers use the "weird" trick line, is because as soon as they see something working, everybody copies it, over and over and over, until eventually it no longer works, then someone comes up with a new original idea that works, and then everyone copies that, and the cycle repeats.
