Sure, most people enjoy humor or wit, but most people aren't as funny as they think, and I think even you'd agree the luster tends to wear off once the top thread on every post is a chain of memes, in-jokes, and stupid puns nested too deep to fit comfortably on any screen.

That is the natural entropic end-state of all large social news sites. HN has anti-bodies against that by downvoting a bit more aggressively than might seem warranted at first glance, but all in all I think it's a wise choice.

"Often humorous and witty comments are my favorite parts of HN"

Then you'll find far better on Slashdot where free speech seems to actually happen, as opposed to here where you're not allowed to joke about anything.
