FWIW both are worth reading. Can we make it a text post with both the main PR and the dissent?

I think it's usually sufficient to include the previous URL in the comment explaining that we changed the URL.

Eventually we're going to build something for aggregating related URLs.

Sounds good. Thanks!

That doesn't work. I only found out about this because a user helpfully emailed hn@ycombinator.com.

Thanks for letting me know! I'll do that next time.
