This is a re-post. I just wanted to find the old discussion again. It's a good article in any case, read it, if you haven't already.

I appreciate pointers to the old discussion on HN about it. Thanks!

The following Google query (excuse my minimal effort including leaving the protocol designation) might be a place to start. I saw a few interesting-looking results. Be sure to click through one one of them where the top comment links to a prior HN post.

Thanks! Doesn't work for this one though, it seems.
