It's about putting up some resistance to the overwhelming trend for forum sites to devolve to Slashdot. If you wan't Slashdot, go there. Most of the same subjects are covered.
It's more about discussion quality. Does humor add to a discussion? Sure. It's good to laugh. but, what happens when the majority (and this will happen) of your replies are just simple grabs at humor? the quality discussion gets lost in the noise. So it comes down to principle, members here have agreed to stay on topic, expand on it, dive deeper, annotate. if you want to throw some humor in the midst of doing that, I imagine that would be fine.

I think this is only a problem if the humor isn't funny enough. I don't know if I hit the mark here, but if I make unfunny jokes I hope I get called out on it (or at least see it reflected in the vote totals), and that'll definitely regulate my posting. If we somehow manage to make enough good jokes to drown out on-topic discussion, I'm going to be very impressed more than concerned I think.
