Basecamp Redesign by @37signals

37 Signals is a great example of a company that understands invisible marketing.
They recently decided to re-design their home page in the hopes that more people would sign up for their web based application, Basecamp. Revamping a web page is nothing new and companies do it all the time. The difference is that the crew at 37 walk you through the process. Why they did it. How they did it. And the results.
Take a look behind the curtain and see how invisible marketing is done.
