Perception is a funny thing, isn't it?
If you type you are "this" tall, people might simply take it as a statement of fact. If you type you are "this" tall using capitalization and an exclamation mark, does your perception of the true statement change your interpretation? Perhaps.
If you insult a man on his Facebook page there are those that may agree, and some who may not. It is generally considered bad form to "defame" the primary contributor to a forum and you may be "invited" to correct or recant. Interestingly your response will likewise influence readers' perception on the nature and veracity of YOUR character.
Stating a fact does not make you a braggart any more than a graceful retraction of words ill-received, diminishes you in the eyes of the viewing public.
Choosing your words carefully, and the forum in which you express them, is all about perception; or so I perceive.
