I looked at my voting record on SO recently, and it's bad. My up votes are barely twice in number that my down votes, and almost all of my down votes are on questions.
I read these posts on Meta, which were interesting.:
Right now, many of my down votes on questions come from the following rule: If I can find the answer in a single google search taken from copying and pasting from the title or text of the question, then I vote it down. Yes, I vote to close as a duplicated when appropriate or provide a link to the external site with the answer. I know I can use my SO voting privileges however I like, but is this a reasonable practice? Should I be concerned that I'm generating far more down votes than up votes on question
