While this is strange for so many reasons (since when do startup CEOs break such high-stakes "rumors" on Twitter?), we'd have to say that, if this isn't some kind of weird account hijacking and the rumor turns out to be true, we're not surprised nor should Facebook be fazed -- Google Buzz was supposed to compete with Twitter and we all know how that turned out. We do however have a few questions, namely has Google given up on Brazilian social network Orkut? At this point it seems as though the search company is just throwing social networking ventures against a wall and seeing what sticks.
