If there's anything I can do to help make this happen (such as digging through your old comments for previous explanations of this point, copyediting, or collecting a petition of people who want to see the post to provide motivation), please please please let me know.

My experience has been that asking people "let me know if I can help" doesn't result in requests for help. I'd suggest just going ahead and compiling a list of relevant comments (like this one) and sending them along.

(If Eliezer doesn't end up writing the post, well, you now have a bunch of comments you could use to get started on a post yourself.)
