On the contrary, I would (be calculating enough). I typically won't make a comment to a thread that is over two hours old, because shelf-life on here is so short, and because I don't think many people will see it, unless it's a super-active thread. Humans (at least this one) like to hear themselves speak, and like it even more when others hear them speak.

The new system actually encourages me NOT to comment on less active threads, because it's going to hurt my "average score."
