I don't understand facebook hate. While it is a bad platform in its current state (for me) because of all the noise, it is also a great platform for many people to stay connected. Their engineering team also seems to deliver some great solutions and plays well with OSS community. As for this deal, I do not understand how they are going to integrate it into their platform or even what they are going to do with Oculus. I would like to think it is a long term diversification strategy because they feel they have great technology.
