Good point. It implies the camera department isn't as important as say the art department / sound dept / visual effects / stunts / make-up - all who get their own section whilst Camera / Grips / Lighting all have to settle for "other crew"!
This is a shame as, in the UK at least, this is an important website for crew as it is frequently used to check resumes. I imagine it's the same in the US?
So I suggest a campaign for change... To contact IMDB and suggest seperate sections for Camera, Grip and Lighting departments contact:
