Hi, I'm the author of jsbin (launched back in 2008) and version 3 is in the works: http://jsbin.com/3/ (though just an open beta).
Interesting feedback in the comments here, just wanted to address some of them:
"where it contains infinite loops" - v3 now strips JavaScript by default, and binds ctrl+enter to run the output with JS. You can optionally enable live JS rendering now too.
"cmd+1/2/3" - v3 has 5 panels now so it takes over even more keys, and although I coded it up, I'm kinda with you that I don't like that I'm expecting to get to a tab rather than a paenl - yet sometimes I like being able to control which panels. I'm considering other shortcuts - maybe optionally disable panel shortcuts (or opt-in?) - but equally open to feedback: http://github.com/remy/jsbin/issues
"tabs" + "stupid auto-formatting" - that's down to CodeMirror being used - and a long while ago I wrote a textarea version of the editor (which kicks in if you're viewing on Android, iPad, etc) - again, this might be a opt-in preference, but I use CM to ensure far reaching IE support because JSBin is primarily a teaching tool, and if a developer is stuck in IE7/8 they need to replicate the bug in that version of IE in jsbin (which is why I can't use ACE, et al).
"ubuntu bugs" - I need to get an Ubuntu virtual machine and check this out - I've heard of a few people having problems in similar environments so I should really check it out.
Anyway, cheers for the feedback (albeit inadvertently :)
