You seem a little harsh on Emacs, but I'm with you in general. (To be fair, Emacs is an enormous pain to get into, has a bunch of legacy cruft, has odd terminology that is difficult to learn, and has a terrible default config. To be fair, Emacs is also leagues ahead of its competitors [referring to Light Table, Brackets, Sublime, and this] in terms of plugins and maturity).

I really just want something with Emacs' principles that doesn't have as much cruft and runs on the web. Light Table seems to be the best bet so far, but this looks interesting as well.
