This article on the use of serious virtual worlds as business tools included this reference to PA's pioneering presence in Second Life:
"How many people click out of a website because they cannot find what they want or immediately see what is relevant to them? To overcome this, the office of PA Consulting in the Second Life virtual world is staffed constantly by a team of Second Life PA avatars in locations around the world.
"It means the organisation has trained "greeters" who can find out more about visitors, what kinds of services they are looking for and offer them what they need.
"A little human charm changes the nature of the relationship between the user and the software, encourages greater interest, more thought. In a virtual world, relationships with customers can be developed through meetings across a desk with an avatar, using an audio or video conversation."
