So, I was bored, and decided to check the reply count on the character threads on TWoP. The results were... interesting. Predictably (with the exception of Abel Koontz), the bottom five were VP Clemmons (3), Dick Casablancas (6), Mallory Dent (6), Abel Koontz (7), and Rebecca James (9). The top five?
Logan Echolls (218) Weevil (135) Veronica Mars (99) Duncan Kane (84) Keith Mars (74)
Well, that's certainly interesting. Logan has more than twice the posts of the titular character.
