Ask HN: Which Sysadmins do you closely follow?

Yesterday krptos asked which developers do you closely follow? I'd love to see a list for Systems Administrators & SREs... or whatever you want to call us.

krptos said it best... The one thing that keeps me inspired, more than anything, is following up with the activities of people whom I consider as masters. When it comes to systems, which sysadmins/SREs do you closely follow?

If you missed it, here's the developers list: https://news.ycombinator.com/item?id=13520891

(I'd be willing to build an OPML file if this gets many responses, does anyone else still use a feed reader?)
