Yes, Firefly's right. I do so often get sidetracked.
cows go moo.
*slaps self* "Get yourself together, man!"
All right. I'm safe.
To the original question "Does an avatar have a big impact on how a person is perceived over the Internet?", I'm sitting on the fence on this one.
My "No" Argument:
I disagree with the statement simply because I myself don't make a "big deal" about people's avatars. Some are nice to look at, some are funny, and some suggest things (which I'm not about to delve into).
Avatars are simply teeny little pictures, with interesting themes sometimes, and let's face it, I live in a country where freedom of speech is applauded. So I will not be one to judge what kind of a person he/she is, based on their avatars; I just accept that there are many individuals in this world, and I congratulate them on contributing an avatar as a small personal statement, saying "Here I am, look at me."
My "Yes" Argument:
I agree with the statement, because people choose avatars, not the other way around. If a person wants to be represented by a cartoon character or a symbol, then it should be taken into consideration that they have willingly chosen it. Therefore, their choice reflects a bit of their personality, because I don't think people would want to use something they didn't want themselves to be synonomous with. The question is "How big an impact". I don't know, maybe some people don't like System of a Down (in reference to my own avatar), so they pin me as a cult leader with bad taste in music, while other fans of SOAD will find my taste superb, therefore making me a candidate for friendship. There are approximately six billion people out there; who knows how big an impact one can make on others, just by presenting their thoughts in avatar-form?
