When thinking of a person to emulate on a virtual chat, it was somewhat difficult simply because I tried to come up with a figure that I would be able to phrase sentences like - to literally sound like them - without having to gove away clues about myself...that was difficult. I think that made my character, Chandler from the TV show friends difficult to uncover. However, when you give away clues about yourself like a guessing game, the idea becomes a lot easier. For instance "the richest woman in the world". There are only a few possibilities 1) Martha Stewart, 2)Barbara Walters, and 3)Oprah. Simple answer. Uncovering Vince Young, however was a little more challenging. He spoke in a manner that you would expect Vince to speak and responded to various conversational topics in that manner also - no one could in fact, figure him out before he started to give clues about his identity.
This exercise really shows the anonymity of cyber chats, even if you have a distinct personality that you are TRYING to display, it can be extremely difficult to do without actually saying who you are.
