I know the URL name is obnoxious, but I have never forgotten this website. Not just because of the obnoxious name, but because I found the information at the site very useful.
Whether you intend to sell something online or you are a potential purchaser, this webpage opens your eyes to the psychology of the one-page sales pitch.
The site is a tongue-in-cheek example of how you get someone to "click here" and buy a product from you. Read and be educated!
The URL? www.clickhereyouidiot.com.
