I spend all of my votes about 60% of the time, and about 5% of the time I dont spend any votes.

I am just behind you level wise, and I have 25 votes a day to cast.

I vote for questions that I would have asked myself, I vote for answers I think are well written, I vote down people who are rude and belligerent, and occasionally I will vote up a "worst node" that I think has gotten a bum rap.
