That is ridiculous. It's soooooo easy to just read posts and formulate thoughtful responses. Guess some people just can't be bothered to do that 10 times a day. I'm to new that my vote doesn't do much so I try to use it to curate more established users. Combining that with thoughtful responses has worked pretty well for me. In some ways I wish comment voting worked differently than post voting. Right now it's rare for discussions to go anywhere in comments, I think it's since people don't see much incentive to do so.
Makes me think of this.
Honestly that picture's text represents a lot of what is happening for some :\
