Nutshell: Leave a bit of explanation when you vote - the idea you save may be your own!
Elevator pitch: You certainly don't have to explain your votes, but providing your reasons may help generate more good ideas. When I know *why* someone disagrees with me, I can address those concerns. When I know why someone agrees with me, I know more precisely how my idea/comment appeals to respondents.
