His first topic / sub-heading answers the question for itself: people are too fussy about editors. Everyone has different tastes when it comes to editors, some want syntax highlighting, some like integrated command line, some just want plaintext.

There are no two people with the exact same preference in editors, and that's why there are too many editors and yet still a perceived lack of quality overall.

It's also why most people end up customising the ever loving shit out of their own editors anyway.
