Most PC users at one time or another have encountered miscommunication online, whether it be via e-mail, message boards or chat. Hence, the births of the douche-chilling "LOL" and those horrid emoticons.
The Geeks and Shrinks at New Jersey's own Human Markup.org (Bringing Human Qualities Into Information Technologies) feel your pain, literally. Further, they'd like your other communicants to feel it as well. They provide an XML solution using something called Human Physical Characteristics Description Markup Language (HPCDML), which they hope will replenish the accounts of the emotionally bankrupt on-liner. This quick sample (avi), while compelling, still doesn't convey the snarky assholism displayed on some music lists I've seen, but I'm sure Human Markup's working on it.
