Kelsey was a leader in product at CoreOS. He did a lot of what you say, yes, but there was a lot more he did out of the spotlight. He spent the most time talking to users and could have been considered their best advocate, for example.<p>I enjoyed arguing with him because he and I were cut of the same cloth and have largely the same goals for the operations industry. He brought some great perspective and experience to product, so I&#x27;d suggest against shoehorning him as a pitchman. I was kind of bummed out to read that people think the demos are all he did, given how much respect I have for him and the work I&#x27;ve observed.
