I actually hosted a demo for that repo in a different server. I'm not saying it's useful to host your own demo (although it could be a temporarily demo deployed on demand). I think 5minfork is cool if you want to try a project and the repo owner didn't put a demo website, that's the problem the author wants to solve and I think it's a great idea specially if you can't get the code and try it locally (mobile browsing?).
