The amount of upvotes a comment earns is a function of how many upvotes the parent submission receives. (Makes sense: the more upvotes the parent receives, the more people will see your comment)
Often I see threads in new submissions which ask for quick feedback to a startup idea or blog post. They would never get upvotes enough to hit the front page normally, and so I would rarely get more than 1-2 upvotes for them.
