He has spoken about it many times in his podcast. In short, Gruber is obsessive/perfectionist/lazy, the current site is OK on mobile with a double tap, making it “just right” would mean more work for him than what it looks like on the surface, etc. He is the kind of guy who took years to choose the right shade of blue slate, still uses Verdana because of the way it looked without anti-alias on low res CRTs running Netscape/IE. Basically, a lot of though on small things to a paralyzing degree.
