Probably simpler to just use one of those "make this page look prettier" browser extensions out there. (typically a part of those "read it later" apps)

I personally use readability for this (though I don't use it for mobile or any other purpose other than "make this pretty now"), and tried it now on pastebin and it seems to work fine.

I've found myself using http://gist.io.

Alternatively, if you don't host your stuff on gist, but instead use raw text files, I wrote a simple markdown rendering site: http://xwl.me

I find it really useful since I can just type out my docs in dropbox, create the rendered link, then pass that around. It's super easy.

Cool idea, go for it. EDIT: looks like delluminatus pointed out that it exists already pretty much.

Kind of like Google Cache you mean?
