There has been a debate with regards to whether or not social media is the death of email or if the two live in a symbiotic relationship with one another. As an interesting piece to the puzzle, Nielsen Online published an article about one of their studies on how social media effects the usage of e-mail.
What they found was not quite what you might expect as they could see a clear positive relationship between the use of social media and the consumption of email. If you have time to critically examine this statement, then visit the article through the link above. All others – eat this table taken from that article.
This relationship speaks in quite the contrary direction of what many hard core talkers in this field are suggesting. But how can they be so wrong? They are journalists, consultants and everyday users of these tools. Why is it that their analysis of what seems to be, or logically might become, in dire contrast with what the data tells us? I think the problem is that they are neglecting the shift in purpose for email.
