Can you please provide a link/source to this? I can't find the AMA'er saying this and a google of parts of what you said only link back to this HN post.

Edit: Ok so it WAS in that thread just not something that the only "verified" person said. I'm inclined to believe it's true however it hasn't been confirmed and posting it here in quotes like that given the title (indicating the person running the AMA said this) is misleading at best.
