Just to be clear, it's fine that you posted this! If checking search would have prevented you, that wouldn't be good. But you could always check search to find previous links to include for curiosity's sake (that's what I did), and to make sure that it hasn't had a significant discussion within the last year.

I've been a frequent lurker since 2008 (IIRC), and saw this article for the first time.

Thanks, it was a fascinating read.
