Most stuff that people think is funny isn't that funny for most other people. So a humor-tolerating, polite community will most likely end up with lots of trying-to-be-funny stuff that's just tired, and signal-to-noise goes down. An option is to drop the politeness and harbor a culture where people vocally heckle things they find unfunny. Third solution is to discourage humor. I like low humor tolerance more than having a low signal-to-noise ratio or low community politeness.
