Have at it! Be sure to follow the instructions at the top of the page.
Also, remember that your annotations should be attempts to interpret, explain, or provide helpful context for this passage. They should not be written as personal reflections. (In other words, they should not read like your discussion or blog posts.) Strive for the kind of "neutral" tone found on Wikipedia.
Remember, too, that you can change what your classmates have written. This is collaborative work! If you want to discuss a classmate's annotation, use "Add Comment." If you think you can make it better, just edit!
Your annotations will take the place of a discussion question for tomorrow's class.
