There is none. I have made this website because I wanted something like Hacker News for finance and economics and there wasn't one.
How long/how much does it cost to run this? I'm curious. Well done with it. Other than a name change, I think this is very useful.
Hosting something like this would be very cheap. A $40 a month VPS could handle it for a while and if it outgrows that then it will be worth something.
True, but thats also because your target market has dynamics very different from your average hacker and even your early adopters behave differently.
