1. The document discusses whether Twitter is killing literacy by examining arguments on both sides of the debate. It defines standard English and argues that Twitter talk is a dialect that evolves from constraints like the 140 character limit, not a cause of illiteracy. 2. Opponents argue that abbreviations and jargon on Twitter can negatively impact language skills, but proponents counter that use of informal language is a choice and that technology has always driven linguistic evolution through history. 3. The conclusion is that while critiques believe Twitter hampers expression, constraints can also foster creativity, and Twitter is not destroying literacy since language evolves based on norms over time rather than any single platform.
