Well Facebook got circles like functionality in no time. They knew the relationships, cities, schools, jobs.

Basically Facebook got to be Google+ parity faster than other way around.

Same thing with Snapchat. Instagram and WhatsApp replicated more of Snapchat than the other way around. Insta won. WhatsApp won. They are growing even though main FB.com is stagnant.
