This is no joke. Google engineer Jon Perlow developed a Gmail driver called "Mail Goggles" that interested users can set to automatically activate during certain times and days of the week. For example, you can set Mail Goggles to activate Friday and Saturday nights between the hours of 11PM and 5AM. Once activated, users have to answer a series of questions testing judgement and clarity of mind. No word on when this will be available to Gmail users, but all of us here are hoping it comes out before this Friday. Spotted by our friends at Silicon Alley Insider.
