A recent Harvard Business Review shows how Pareto applies to the number of Twitter users who are actually generating Tweets. It suggests that 90% of all Tweets are generated by only 10% of users.
This would seem to suggest that Twitter displays the failures of traditional 'broadcast' media where the there was a 'let's see how much of it sticks' approach to messaging.
Where are the examples of Twitter really making an impact as contributor to Social CRM? Surely being social is about having conversations with many people...not using a loudspeaker to convey a message into the ether ?
