Sample Book Insights: #1 The endorse feature allows users to endorse skills of others. It works like this: on your profile page, you can endorse skills of four people you know. On someone else's profile page, you can endorse their skills. #2 The feature is innovative and easy to use. It gets more profile data. However, the data is not always accurate. It also has a heavy sampling bias, as friends are more likely to endorse each other than strangers. #3 My favorite product is my iPhone. It meets my three criteria for great products: it's useful, innovative, and easy to understand. #4 The Apple's hockey- puck mouse from the 1998 iMac is a good example of a product that was designed poorly. The round shape made it hard to orient, and the blue accents on the left and right did not deliver any additional function.
