Ok, fair point. I thought it might help to make a public comment in this case because repeated private requests don't seem to have worked.
The jokes thing is a tricky one for HN. I love comedy and I love wit. I'm sure most of us do. But when you're optimizing for signal/noise ratio, as HN tries to, there are tradeoffs. On the whole, I think the community habit of downvoting most (not all) jokes is reasonable for what HN is trying to be.
