Welcome to Gaia! ::

If you notice the formatting styles in Gaia, it provides some options that allows some ideas to be implicitly expressed.

A red colored text is most often considered as important message, but in this case it is not as important.
IF I TALK LIKE THIS, I seem to be shouting although I am not.

In such cases, we may disregard the content at first sight of the text because the brain focuses on the most evident aspect, which are the color/all caps and other features. These examples show that regardless of the meaning, the format of the text can immediately create a certain response from the readers.

Because of the power of the visual arrangement of words, some statement create an implicit message and these implicit message can be used in various ways.
If you observe the minishops subforum of Gaia, most shop owners decorate their shops with text formatting. Besides this, certain formatting is followed in some academic subjects because the visual arrangement may make it easier to read. A research experiment also shows that readings written in larger fonts more easily memorized than the small fonts. Font styles can also create different interpretations- scripted text seems to look quite academic while "gangster" style of writing carries with it the "gangster" feeling. There are many other ways in which the text can be manipulated in terms of formatting and each of it may create various reactions.

The format in which a text is written creates a certain aura that makes people react to it according to its visual arrangement. What do you think?

How easily the brain is fooled. Try finding info on people who have a conglomerate of senses (they "hear" the color red, or smell a picture of a ball). I forget the term, help me out?

Yes, I totally agree. Also, I think that itallics imply a sneer or are heavy-set with a normally-concealed emotion, as it may be somewhat context-sensitive, like the X button in Halo (XD Halo!)
