How Google+ is built. Is Google's Hangouts Its Killer App? Gmail+: Google Already At Work On “Several” Gmail/Google+ Integrations. One of the factors that led me to conclude that I could walk away from email for the month was the emergence of Google+.
It’s yet another network where people can now message me if they need to get ahold of me. Further, Google+ makes Gmail look like even more of a dog. Google Plus is Eating Startups. Google Plus, the ambitious company-wide social network launched late last month, was reportedly built in secret over an extended period of time by scores of engineers and social software designers brought into the company through a campaign of heavy hiring.
The scope of Plus's ambition is far from fully realized, though, and apparently the expansion of the team isn't complete yet either. This morning a well-backed little startup called The Fridge announced that it has been acquired by Google and will close its group sharing app up to work on something similar at Plus.
