In multiple places on github, as a vim user, I occasionally instinctively hit escape. Github sometimes closes a comment box and I lose all the stuff I had been typing. It's an unfortunate UI issue for me (and probably others).

Just use VIM proper; after all, It's All Text! https://addons.mozilla.org/en-US/firefox/addon/its-all-text/

(alternatively, use Pentadactyl and press C-i when the focus is on a text box)

One of the several reasons that I use Ctrl-[ or Ctrl-C. ;)
