What are the differences between Google, Facebook and Twitter?

Here are basic simplified definitions of each:

Google – Google organizes and finds documents and media files that are stored online.

Facebook – Facebook helps you feel more connected to people. You share your life, pictures and stories with your friends and family.

Twitter – Twitter has tapped into a new source of data, one that never before existed on the internet: sincere opinions from real individuals in real time.

A platform that I like to define as;

“An online mastermind group where you get to pick the conversations you want to be involved in.”
