This week’s nugget comes courtesy of Business Week, which describes a new way to calculate the cost of meetings. Payscale.com has launched Meeting Miser, which utilizes the Web sites’s database of 10 million income profiles to estimate meeting participants’ salaries. A user enters attendees’ job titles and regional location, which enables an electronic meter to calculate a collective “cost per second.” The meter can also be projected alongside PowerPoint slides which, you guessed it, can help energize a ho-hum presentation.
