yp> this is Internet, where everybody is a liar. :)
well, I wouldn't necessarily go *that* far.
perhaps it's more that those who would be malcontents and ne'er-do-wells offline, are more prone to be such online, magnified.
anonymity affords some the courage they wouldn't otherwise have, like the whiskey bottle that fuels (and eventually rules) the undisciplined drunkard.
imo, it boils down to the person's character and integrity, really.
if they're heartily genuine in person, they're likely to be as authentic online.
similarly, if they're a whiny asshat in person, well, the Internet won't make them any better.
a bit of Kipling may be in order.
