Now this plugin uses metabox.it as its default pastebin
Usage is pretty simple, you just hit a keybinding (default is Super + m) and press ctrl +v to paste the link with your uploaded code. It will display a link in the statusbar when it's done uploading.
If you have a selection in your file, it will paste the selection, if you don't, it will paste the entire file contents instead
Issues right now are that it doesn't support foreign characters, I need to figure out a way to encode the output to utf-8 somehow. But I hope I'll get it fixed soon.
There you go, install instructions are in the README on github
