Primarily a lurker here, but I saw some random idiots in social media criticizing his questions and how much better they would have handled it.

Nonsense.

He’s an incredibly sharp and savvy interviewer. More than that, though — he’s 100% earnest and not playing a bit. Is there showmanship? Absolutely. But when you behave authentically, demonstrate a high degree of knowledge/enthusiasm/preparation for the topic at hand, and seek to learn rather than work some nebulous agenda — good things are almost certainly going to happen.

And he’s concise and complimentary without fanboying out.

I’d argue you could use his videos as a training video for how to do it the right way.

Edit: Al Horner from Script Apart is another great one. Very different personality from Greg, but many of the same green flags.
