Laurel/Kostelnick 2.0 Q's

1. How does Laurel's suggestion that computer users are not passive observers when interacting with a computer (instead, they are actors) relate to the social-constructionist's perspective of language?

2. What are some ways that humans have taken ation in representational worlds since the Laurel article was written? (I'm thinking specifically representational worlds on the web.)

3. Out of the six visual rhetorical strategies that Kostelnick and Roberts list, it seems like ethos is overlooked/mishandled more often than arrangement, emphasis, clarity, conciseness, and tone. Why do think we have a natural tendency to neglect ethos in visuals, or does that tendency actually exist?
