>I became more afraid of the sustainability of newer editors [such as Textmate].
I'm not afraid. After 22.5 years on Gnu Emacs, I'm considering a jump to Textmate 2.
(I probably would not be considering a jump, however, without the boost to sustainability caused by Textmate 2's having been open-sourced. ADDED: also, being able to edit files on remote hosts is not important to me.)
I gave Sublime Text a shot (20 years emacs), but ran into the same thing that has kept me from using emacs x11 for more than a few weeks at a time, which is that I spend maybe 30% of my time editing files on remote machines, connected over ssh, often through complicated tunneling arrangements that make using Tramp a pain to use.
I keep thinking that what I really need is to switch all the machines I use to Plan9 to abstract away the remote sessions, I guess then I'd have to learn Acme :)
