The internet may kill religion, but it doesn't kill faith. Religion being defined in this instance as cultural observances, unquestioned metaphysical assumptions and ceremonies, and faith as things one deeply believes and part of who you are, not merely what you do (to fit in).
And, I suspect, most people of faith who have thought about it deeply have no problem with that. I'd much rather people were sure of what they believed, and actually thought about it, argued about it, and made a real statement about what they believed, rather than just accepting what they are brought up with.
I think that the internet - and in fact any meeting with outside ideas - is the best way to kill nominal 'religion'. However, I'd make a guess that many people actually find a new faith, or find their faith hugely challenged or restructured. I know formally agnostic people who got into 'new age' mysticism and became (in some form) Buddhist through reading and learning online.
I am a follower of Jesus, who I believe is the son of God. ("Christian" being a very loaded term, especially in the USA). Many of my friends and others who believe the same as I do have been strengthened in their faith by discussions and videos online. Many churches don't bother actually exploring scripture in a critical or even structured way - but plenty of people online do. Video serieses by John Piper, Rob Bell, Nicky Gumbel, John MacArthur, and many other "thinking preachers" have been instrumental in my building a faith which is able to accept alternative viewpoints without freaking out.
C.S. Lewis was an Athiest, but became a Christian at university, and encountering views which challenged his view of the world so much he had to re-examine his own philosophies. I know plenty of others who came to faith at university, and a few who did online.
So. I'm a believing, 'born again', totally convinced Jesus-freak, with friends who are Athiest, Buddhist, Muslim, Agnostic, straight, gay, married, divorced, rich, poor. Their views do not destroy mine, and I will not try to destroy theirs. And I accept the fact that my views can only really be solid if I can engage with them in civilized discourse, and can understand and appreciate (even if I totally disagree with) them.
To those who call themselves Athiests here - how many of your friends hold views as strongly as you do, but which are completely contrary to your own?
