@mschwarz I’ve done an edit pass on the article. If you want to review it again now is a good time. I broke up some rather long sentences and removed some passive voice.
I also changed “big heads” to “notable folks”. “big heads” could be taken wrong, in some cases, although I think I know what you meant.

I’m putting together a featured image and intend to publish it later today (USA Pacific coast time).
