I really enjoyed this article. I have been eyeing up Discourse for a while now. Heggen's quote,

"You should strongly reconsider whether it’s worth having a forum at all, because in my honest opinion a forum is an ‘all or nothing’ sort of deal. It’s either a key component of your website, or it’s going to become a graveyard quicker than you can say ‘Welcome to our community!”

really made me consider my forum situation.
