Comment votes are a tool for grooming the discussion. Discussion on most threads ends after a day or two. What's the value in downvoting a 3-day-old comment? Very few people are going to respond differently to the thread as a result.

If you want to participate, you should write comments, or, better yet, submissions of your own.

By your reasoning, you think it shouldn't be possible to upvote comments after a couple of days either then?

I don't think it should, no. There's a big halo effect to karma, and disabling upvotes for stale comments might mitigate it.

But it's not a big problem.
