Kelsey is all over the Internet talking about Kubernetes and at the time of this writing was a Product Developer Advocate at Google. I continue to see him cited and learn of him on podcasts. If something is tending in K8s land, he’ll likely know about it, even though I get the sense that he might not be as connected with emerging/incubated innovations in the space that are mostly just discovered by watching what engineers and developers are working on themselves.
