What's the difference between this and Emacs?
On top of that I can be up and running with Emacs on a fresh install of just about any linux distro: install via the distro's package manager, drop in my configs, done.
It looks like the GH guys have worked around this problem quite well, and I'm looking forward to begging, borrowing, and then just begging again if I get a chance to try it out.
Not sure if that's an unfounded fear, but I don't want to invest time customizing a platform and writing plugins when it could close shop in a second. I suppose I could say that about a lot of things I do customize, but it's hard when the FOSS text editor world is so rich.
