Ask HN: I own mrrobot.io Should I build something on it or sell it?

I have an idea to build a great website which is inspired by http://3564020356.org/deserve.htm but the hacks will be related to the ongoing series. I'm not sure, if I should go ahead and build it. Would it kick off? or should I just sell it? I'm inclined on the idea to build it. I asked a few friends around who weren't much impressed. So I wanted to ask more like-minded people. What do you think?
