The only thing that stands as a non-contribution is your need to publicly proclaim a lack of a sense of humor.

I think HN still tends to reward quick posts over more thoughtful ones. As humor is quicker to post, it will come to dominate (i.e. HN will become Reddit) without this important check/balance in the culture.

As far as value added to the conversation, the joke added more value than the sarcastic passive agressive response did. HN should be more concerned with monday morning quarterbacks than people who add a new facet to the discussion.

It's occasionally helpful to explain to people why they're being downvoted. Comments that consist of pop culture references usually aren't treated kindly.

Yeah, right?! Why so serious?

Now, seriously talking. A joke doesn't hurt a discussion. Laugh and move on. Or even better, keep making jokes.

Why does it say "paper jam" when there is no paper jam?
