Personal worth

Ever pondered the real value of your contribution to your workplace?  The 'good' news is that some companies, reportedly with IBM and Microsoft among them, are apparently measuring just that for each employee.  The key currency seems to be (non-verbal) communication and the greater the measure - the greater your value:  better to be one with a large dark-coloured circle - 'thought leader' rather than a small pale circle 'not contributing a hell of a lot''.  (Thanks to Slashdot for the article.)
