I always vote my shares.
Knowing that the majority of shares are voted without any significant research, and along management recommendations, I always vote to throw out the board, and to deny their requests for more compensation. And I usually vote for the shareholder proposals, even if management says not to. Very contrarian here, but I have some reasoning.
The way I figure it, the wild majority of shares are voted along management's recommendation. But let's say there is a bad apple or two and there's a campaign to oust them. I could either spend a lot of time to discover that there IS a campaign, or simply join it by voting against all of them.
