@GordonS It's an HN convention for the title. If you would delete your comment then I think I would be allowed delete mine and would gladly do so now that the submission has been "fixed".

Of course an algorithm like this is evergreen.

If you click the "x minutes ago" link on any comment you can reply directly to it without having to wait for the "cooldown".

But I think if I reply to him then he can't delete and the whole thing recurses.

I am sorry for this derailing.

I know there is a convention to put the year in the title, but I thought it was only used if the date was actually relevant to the article?

No, it's also a handy way to show readers that this isn't something new. E.g. some readers will love to read anything new that Scott Aaronson writes, but wouldn't necessarily want to read something old or that they read in the past.

Is the date really relevant for this?

By default, readers assume that anything linked here is recent.
