This poor, poor girl had the unfortunate task of being the permanent "booth girl" attempting to attract new users to join the service. But it honestly looks like they hired a mall photographer to take a glamour shot. The shadows from poor lighting make her look old and unattractive, instead of youthful and inviting. You can tell she's a young vibrant person from her smile, but the photo screams "I was manipulated by a Photoshop LE user!" It's overly sharpened, overly saturated, and overly bad.
I think we should save her. Write to 37Signals and let them know that good photography is important. Yes, it's not as cheap as using your point and shoot with some desk lamps in the conference room, but to the people you are taking photos of and sharing with the world it's worth every penny.
We can't let them get away with this travesty of taste any longer! Save this girl!
