Questions to consider:
What are the character's main interests and hobbies?
What would this individual share about him/herself in the public eye?
Who are the character's friends?
Who would the character interact with online?
Or:
You may type a one page (12 pt. font, double spaced) letter or journal entry through one character's eyes. For example, Jody could write a letter to Mark Brittain, or perhaps Sarah Byrnes would write to Ms. Lemry about everything that's been on her mind. Remember, it's important to remain in character and stay true to the way that character thinks, speaks, and responds to things in life.
