We've been using Medium for all our PH blog posts and announcements. I've considered embedding a medium collection within a subdomain of producthunt.com but this is much cleaner.
As Medium's network grows, it may become a distribution channel people and companies cannot ignore, similar to Twitter, Facebook, etc.
I moved my entire blog to Medium a few days ago, and it's much better now than using WordPress (in my humble opinion). I've combined Medium resources to create my personal website there, it looks great: www.reynard.com.br - there's also a tutorial on how to make yours.
