Number of project failures and cuts under Larry Page is just amazing. Normally you would expect that founder CEO insist on long term vision and loves to go after big bets. Under Larry Page, X had been cut. Boston Dynamics was lost. Robotics effort was shutdown. And now G+. After all these time no one at Google's highly paid smartest on Earth visionaries were able to experiment, try something new and continue fight fo…
What? They spent a decade on G+, launched it with much fanfare, annnd it just didn't pan out. Sure, they didn't drive it down Google users' throats as aggressively as they could have (via e.g. Search, Chrome or Gmail) but that really wouldn't have helped them - Facebook didn't grow like that either. Social networks need to grow via organic growth, via word of mouth.
