I'm thinking of starting a discussion forum over at my Gifty.co.nz website. I've never liked heavy and ugly phpBB-style forums. I'm really keen on simple and minimalist, so I like bbPress. And PunBB looks okay.
But something with the simplicity and threadedness of Hacker News or reddit would really be great.
Does anyone have any ideas or experience?
They're both open source and you could alter it so that submissions couldn't be links if you so chose.
