My online personality has both similarities and differences to my real life personality. Online I am slightly more quiet, responding only to what is said, whereas in real life I am very talktive, a little hyper and energtic. I am a peoples person both online and in real life (after all I do work in retail :P). I also am way more sarcastic in real life then online, as I am more careful when I allow my sense of humor online, since it can be taken the wrong way in text. In real life, you would be able to tell from my voice and facial expression that I an being sarcastic. That is one major difference to me in real life and online. I am also a bit stubborn on in real life and that does shine online at times as well

So yeah in real life I am both similar and different to how I am online. ;)
