Have you noticed the extremely larger number of non-believers than believers on the internet, even though Atheists are a minority in the world? I think I might have a conclusion for this.
It is my theory that to believe in a religion, you must not have time to pause and take a good look at what you are believing. Let's face it, this world is a busy place! Most of us are too busy to answer deep questions like, "What is the meaning of life?" I think that when somebody gets the time to think about their beliefs, they grow apart from them, when they notice how silly they really are. These people with extra spair time may inhabit such places as the internet, more than people who don't have enough time in the day. This would explain how Atheists are the majority on the internet, but a vast minority in the streets.
