Or rather, why is it that people tell you more about themselves when they don't think you know who they are?
I mean, put a couple monitors between two people, and suddenly they're spilling life stories to each other, and being who they really are... Sometimes really sweet people, and sometimes shallow, narcisistic idiots? I guess it's that the internet is somehow less personal... Without the real sting of rejection, people can be who they are...
But why do people fear that rejection? Blah. I'm not saying anyone should be less open here... But what's so wrong about being more open there? Why hide who you are because you see someone? Why change how you act because of a monitor? The 'net is no different from anywhere else, except that you can see a bit more about how people really are (I mean, really, suddenly every guy turns into a cat callin' construction worker, lol, and every woman is a seductress vixen, go figure)...
So get out there, and say hi to someone... Whether it's online, or out there in the real world. Most importantly, have fun... That's what it's all about.
