you don't have long to make a first impression

We've always felt you had a few seconds to make a good impression, but research shows you have even less than that...

Web users judge sites in the blink of an eye.Potential readers can make snap decisions in just 50 milliseconds.: "Like the look of our website? Whatever the answer (and hopefully it was yes), the chances are you made your mind up within the first twentieth of a second. A study by researchers in Canada has shown that the snap decisions Internet users make about the quality of a web page have a lasting impact on their opinions."

thanks to seth godin, for rooting this out. in his book the big red fez, he said you had three seconds, now it's even less than that

what's the takeaway for this? you need simple, clear (landing) pages, and i believe you also need clear print materials. single minded focus, clear communication, uncluttered pages whether in print or on the web.
