I don't use facebook much though I have few friends who are much addicted to facebook. I prefer other ways to get connected to them. However, honestly I've tested it and I don't like their upgrade or new development. I feel so many things to see at a time so Google is really innovating. Google is quite familiar than Yahoo. I personally like Google plus more than facebook because of it's good features and it has different features than facebook. I guess it is helpful to some businessman.
