I like Google because you use it only when you need something, it feels very natural, how an online service should feel.
With Facebook I have feeling that I use it mostly when I don’t need anything, basically bored, and to me this is main distinction between Google and Facebook.
The idea that social networks are helping us to connect with our friends and family is totally flawed. If I want to connect with my brother in Croatia, I would simply give him a call on Skype, the conversation would be far more meaningful than empty chat exchange on Facebook.
All I want to say, I have to lay off from social media a bit :-)
