do you think  

A little
humor is nice. I would expect it to relate to the subjects we discuss here. Some people have an unfortunate concept of humor, of course.
Who worries, as I do, about all the serious personal injuries we don't see, on those "Funniest Home Videos" TV shows. . .? Not the producers or advertisers, apparently !
One person's idea of "funny" is someone else's revulsion, or obscenity. Maybe you could be more specific ?

Have you heard the one about the chairs?
I wasn't kidding about my sexy chair. And Riki might be swiping that Bertoia as I write.
And that story and conversation about swiping the chair from McDonald's was hilarious!!!
Is it wrong to laugh over "serious" design?

wit
is the soul of human endeavor. wit is the soul of humor. therefore, design can be funny ?

There's lots of humor here
People create a thread and post something...and then people make comments on the topic. Some are funny, some are negative, some are positive.
