Editor's note: Aaron Travis is vice president of user experience at Citigroup and CEO of PolySuite.com. When starting a new web or mobile app, you may find yourself confronted with an instructional walkthrough illustration or help text indicating how to use it. If you are a technophile who looks at new apps every day, you might quickly dismiss these aids and wonder why designers keep adding these things that just get in the way of using the app.Source: http://feedproxy.google.com/~r/Techcrunch/~3/usbEgwb-LTs/
