For now, I get 16 votes a day and usually manage to spend them all before noon time, and that's just on the upvotes... I'll see what happens when I'll be getting over 30 votes a day :)

 

P.S. I don't downvote since I believe that it is more useful to encourage a good post than to discourage a bad one. Someone who posted a bad one will eventually learn to post a good one... but someone who posted a good one should realize it is a good one (to remember how to post good ones) and upvoting is a good way to do this.
