I agree that extensibility is a great thing, that's why i spent some time learning emacs. But unfortunately no amount of elisp could fix the bugs in core: jumpy scrolling, and keeping cursor always on screen. And more importantly after some time it turned out that i used all that extensibility mostly to get on par with other editors, so to me emacs felt more like a construction kit for a violin rather than an actual violin. Hopefully new generation of browser based editors like cloud9 or atom will provide extenibility similar to emacs, but will start from more sensible place.
