This may not be the common census, but I've always felt safer sharing secrets about myself with people online, whom I do not know outside of the internet. I figure that I'll never meet any of you, and you're very easy to escape from if you turned against me. However people I know outside of the internet are much harder to escape from, and if I make one wrong decision to tell one wrong person something it could spread like wildfire, and be hard to escape. An example would be that users here knew that I was a brony months before the majority of my friends did.
How about you OT?
