Aerodynamics, weight, aesthetic clutter and just how superfluous they are. I've got 32/32 spokes on the wheels of my tarck bike, but I would probably be fine with 12 on the front and 20 on the back. The weight saved and aerodynamic improvement of 12 bladed spokes over 32 rounded ones is quantifiable and significant.
I realise I'm lucky that I'm closer to Quintana than Kittel when it comes to this, so wheel stiffness isn't really a problem, but you know... marginal gains and all that.
