I find patch reviews on #github rather awkward compared to reviews on good old mailing lists.
Why do people do this to themselves?
contributor: "here's a patch"
reviewer: "waiting for rework"
contributer: "huh... what needs to be done?"
reviewer: "see review comments (on the github issue page)"
contributor: "looked around but I don't know which page you are referring to?"
reviewer: "had to press a button, damn GitHub UI, hate it"
