> I even briefly used a tiling window manager before very quickly returning to the floating ones; the appeal of such utterly inflexible window management I will simply never understand.

The author mentions this design in passing but I think it is contextually important to understand why people might like this at all so I'll share what I appreciate about tiling window managers:

The appeal, for me, is the inflexibility. Tiling window managers and their often bundled 'tags' approach to window management offer a simplicity that is comforting in its constancy to me, the user. To sum it up, they make me feel 'at home' using my computer. Comfy goes beyond familiarity though.

I never have a mess of windows to deal with across my monitors, where I'm constantly needing to look at a taskbar, minimizing and un-minimizing programs (or looking through a stack of 'shaded' windows in the author's case). Each of my frequently used programs has its own tag, or shares a tag (visually as a tile) with other programs. While the programs I have open at any one time change, their locations don't. Everything in its right place, I always know what is where. I switch between all programs directly with ease, with no intermediate interruptions to occupy my attention, my hands never leaving my keyboard. No 'looking' for stuff. Switches happen instantly because there are no transitions or any other forms of detectable latency (and for that matter, no compositor either). Combine all this with extensive use of scratchpads for ad-hoc and exploratory tasks and all the bases have been covered. Comfy.
