re: releasing a revision - I agree that writing a new piece and then putting a link on the top of that article is a good idea. I'm against hiding failures, I think they're important to role model, so don't like the idea of taking it down.
On writing it, I don't think I can or could write it. I am sleep deprived and my primary responsibilities are with @Ziva and @Alanna, and this work obviously requires care and time.
Would anyone like to take up the mantle of writing the clarifying piece?
I would love to support by contributing or editing, and I'm sure others would too. I just can't be the primarly person expected to deliver anything at the moment.
