I think the problem is one that has been around since the invention of the printing press and the subsequent widespread use of books, newspaper articles, etc. It's always been a challenge to convey a specific tone of voice through a reading medium because all the reader sees is the words on the page. You don't get the speaker's tone of voice, hand gestures, body language, etc. that you normally would by speaking to someone. It's through these subtle gestures and voice tones that people convey satire, a sarcastic attitude, or an ironic statement. Because the reader lacks these signs of a satirical statement, the statement is misinterpreted as seriousness and a keyboard fight breaks out. What would fix this is a standardized punctuation system capable of conveying these emotions through text alone, such as a unique set of quotation marks to indicate satire or sarcasm.
