Now that the notion of presence is beginning to infuse our electronic communication, an inevitable next question is: presence where? Marc Eisenstadt, chief scientist at the Knowledge Media Institute of the Open University in the UK, wrote to show me a Jabber-based system called BuddySpace that locates presence indicators on maps. In the map shown here, Marc (top row, third photo from right) is present in the office, but idle. Martin Dzbor (bottom row, far right), KMI's “chief presence architect,” is present and active. And that little dot on the US map, in New England, is me, present and active.
