Thanks Kesh… I think it all depends, if you are meeting someone for the first time you would behave differently anyways since the comfort factor is not there and in this case it has got to be a professional conversation. But you are spot on with a two-way interaction idea… a person like me is more comfortable talking to a real person, but others still want to move over the nervous phase first. Maybe an ideal situation would be a mix of technology & human intervention.
