In the Create A Homepage assignement I was marked down a couple of points because the site didn't tell the lecturers anything about me. I have reasons for not putting too much of myself on the Web. My public face is what I want people to know. My close friends know more about me.
I asked at the uni about this, and I was told I was permitted to put false information about myself into the assignment.
But then they still wouldn't know anything about me.
