It appears that Sequoia's new Grove system doesn't allow user commenting. Which is somewhat of a shame, as it makes the posts very one-sided and unopen to debate, which is what appears to be happening here in the HN comments.
What about the comments here do you think is useful to them? The orignal post was about how to deliver a useful presentation, presumably to them but probably to a more general audience, but the comments here appear to go off on a tangent about selection bias.

(That said, I totally understand getting content rolling before adding comments)
