I'd recommend checking out Telescope (http://telesc.pe/), it's a very feature-rich news site in the style of hn/reddit, it's very actively developed, has a decent interface/design built-in, and can literally be deployed just by clicking a link (though you can host it on your own server if you want). Many news sites posted on hn tend to use telescope for these very reasons.

You can find out more here: http://telesc.pe/

And launch your own instance through Giteor here: https://giteor.com/deploy?git=com.github.SachaG.Telescope.ma...
