I noticed recently that voting seemed to be sparse, particularly on questions.So I ran a quick query on programmers and found these results:
NumUsers AvrUpVotes AvrDownVotes AvrDaysMember
-------- ---------- ------------ -------------
432 280 19 123
This is the average up and down votes for all users with a reputation range of 1000 to 10,000.
We users in this rep range are supposed to be the healthy voting middle class! So why are the average votes for us so low? At 30 votes a day, and an average membership of 123 days, there could theoretically be an average of 3690 votes per person! In practice, there must be less, because you may not find anything useful to you on a given day. However, I suspect that we all see more than 2.28 things a day that we find interesting. An answer doesn't need to be funny or catchy to be good, and if you think a question is worth answering, you should vote it up.
I realize that most of us are only moderately active. But surely we all can find more than two things a day to vote on. If you see a question that interests you, vote it up. If any answer is helpful to you in understanding an issue, vote it up.
Exercise your right to vote!
