I'm afraid that I'm in opposition to this as well - many of the points in Robert's answer to your other question apply here:
If it isn't already obvious from the voting, I just don't think you strive for too much "pointless" fun running through your front page. It's going to set the tone of your site for a lot of folks for a long time to come.
But +1 for spirit points.
Imagine if you came to this site for the very first time, and found the front page full of Haiku questions - would you come back? It's rather hard to phrase a good question in the form of a Haiku - forget about answers. Let's let mSO keep the Haiku thing.
