Google Buzz
Unsure of its ability to successfully roll it out as an independent product, Google must have then decided to force feed Buzz through its Gmail user base of 175 million. Google executives likely reckoned that in a single day Buzz would garner more users than Twitter has been able to in two years after all that celebrity publicity. That really is why Gmail users woke up one day to find their private account details exposed to the public, unannounced and unprepared, because without such default exposure Google executives likely didn’t believe they could deliver a critical user base for Buzz. That’s not “improper testing,” it’s a platform strategy.
