Compare a site which has users use their “real names” with one which allows “fake names” (anonymity), e.g.
and comments are anonymous, whereas and the are designed for real names. You should explain how they talk to each other in a different way, including specific examples of what is said and their “names.” You could compare them considering:
What is their tone and language like?
Are discussions supportive or argumentative?
What kind of posts receive the most replies?
Do you trust information equally for both?
