When you put it that way, I see what you mean...

Most people need some kind of incentive to keep devoting time to something. As meaningless as it might seem, upvoting is at least some kind of show of gratitude (commenting is even better) and provides them with enough feel-good brain chemicals to encourage them to keep submitting articles.

Commenting causes threads to rise and makes the site look healthier... even when the comment is relatively redundant like this one was, it enables users to read the other comments in the thread because the more comments a post gets, the slower the post will drop and the more people will see the comments.

A lot of times I have nothing valuable to say but say something anyway just in case it encourages replies and leads to something valuable.
