Yahoo has added an intriguing feature to its Messenger software that will have bosses up in arms but allow malingerers and timewasters to save their skin. Stealth settings, Yahoo claims, will allow users to hide their online status from their boss, for instance, but remain visible and so chattable to their friends. It all sounds like good clean fun, to be honest, they should call it skive and hide. One thing that struck me though…how many bosses use Yahoo Messenger anyway? Haven’t those in higher places been persuaded to run Skype these days?
