1. Linkedin – Professional networking only. Try and remove all your friends from your network there and focus primarily on building business networks. This will not only seem professional but will also avoid creating a difficult situation (for e.g. if a person who is barely known to you asks for a recommendation, what do you do?).

2. Facebook – Friends only. Please, please avoid adding professional networks here. Remember, one posts various pictures and views that are sometimes frivolous, trivial, and perhaps just whacky. You do not want your next recruiter to read/view these. (Note: Sometimes there is a grey area – friends who are also business contacts. Feel free to add them to both Facebook and Linkedin – that is fine)

3. Twitter – Open an account only if you have anything meaningful to do with it. If you don’t have anything reasonable to say, please don’t post. You can follow all you like – you may want to follow a marketing guru who tweets about trends, a technological evangelist who tweets the next big thing, or a fitness freak who tweets healthy knowledge. But the space is clouded with folks who have nothing meaningful and are thus a waste in this era of increased productivity.

I recently finished reading the book and I have to say, I am greatly impressed. Stephen starts with asking everyone of us as to how much in our opinion do we leave a trail of data ‘explaining’ our tastes and behavior. Our clicks on the humble IE/Firefox/et all are getting captured and monitored by numerous numerati (number crunchers) to understand and gain information about us. He then goes on to mention how marketers are using the same data to provide us with targetted, contextual advertisement to get our business.

Then the author takes us on a journey – as a patient, blogger, lover, and even a terrorist. How the different companies and agencies are tracking information that we unconciously and willfully give to clearly identify us. Clearly many of the applications and systems designed are going to be for our own benefits. But an ethical question is also raised – Do we really want someone to process the information and join the dots to know a private ‘us’?

The digital age is changing the way businesses evaluate the needs of their customers. With the advent of Google and other data rich companies, a completely new discipline that intermixes core skills such as statistical analysis, anthropology, psychology, et cetra is taking birth. What this sector is creating and what impact will it have on our lives is the basic premise of the book. The book is organized very well and provides for an easy read.
