Who is moviereel? And what does he do? I find him everytime I visit the chat section. I beleive he is not a human like community. If so what does he do by posting the questions in chat?
Movie Reel is one of two message feeds into the chat room - the other being Tomato Bot. These are just automated services. The purpose of Movie Reel is to bring to the attention of chat users of a new question being posted.
You can see information about the feeds here.
