I have lots of criticisms of a stack type of system. It should be reset more than once per year, should be light hearted, and one big part of it should be being a team player, etc. My point is just that it's easy to have the whole team become fairly complacent and start focusing on other activities. Do you want your star team member spending all her time collaborating on a non-business-relevant fun project, or pouring that energy into work stuff to earn the $50K bonus.
