Cynisism and the Web

I admit to being cynical sometimes in my writing. I think that it stems from my occasional wanting to be accepted by complete strangers on the internet. It is much easier to criticize strangers and fall in with the cool, cynical crowd than to actually admit that I might not understand something or admit that I am floored by someone else's achievements. I don't really like people in my real life who are cynical, so why do I get cynical on the internet sometimes?
