(its "smart ass" btw) The catch however is, that through a bug in Google calendars the names of all registered Gmail accounts are now readily available. All you need to find out the names of any gmail address is a Google calendar account your self. Depending on your view this ranges from a harmless "feature" to a rather serious privacy violation. According to some reports, spammers are already exploiting this "feature"/bug to send personalized spam messages."
