Known Ravenclaws: Rowena Ravenclaw, Luna Lovegood, Cho Chang, Professor Flitwick, Roger Davies.
Good points: Intelligent and wise. Library is your domain. Never get labeled as "the dumb kids". Reading Hogwarts, A History is considered a good thing. Eagles are generally cool. It's the focus of this site and my fic.
Bad points: Considered nerdy. Get no recognition of note until Book Three. Never even sorted/seen in the movie.
