"Amazon's data-tracking software watched what else these people purchased..."<p>We know this is a common procedure at online stores and social network services.<p>Still I was shock from watching myself using facebook and experience the way it works.<p>I am using facebook to keep in touch with my customers.<p>And very often names do appear multiple times. So who is the right person?<p>Very easy...
facebook in combination with a human sense of your customers habits it is a very strong tool to keep in touch with somebody you know. I was amazed by myself how easy it is to get the right person out of 10 just having a shot look at their timeline.
