I think perhaps if a person spends so much time on a chatboard that it ends up being detrimental to their work production, or ends up usurping all other potential for a social life, or ends up being the place where they devote much of their emotions and energy, then perhaps they need to step back and put less priority on their online life.
I don't think that posting on a chatboard necessarily makes one a "loser". Putting too much priority on it could possibly lead to "loser" qualities.
