We worked with @joebuhlig to try implement the voting buttons on the front page - but it turned out it was not as easy as we thought. So we’ve put that on ice for now.
So the plan for our site is to use plugin, Topic Previews, to display a like button on the front-page and we’re currently working with @joebuhlig on building a ‘hot topics page’ which is using a similar algorithm as Hackernews to sort topics. It should be done very soon and released on Github when ready.
Below how we plan to implement the like button on the topic list on Dansk Dynamit
Our dream is to completely customize the like buttons on discourse to maybe even change the name to upvote and maybe even change the markup to accommodate interaction animations like this one that i mocked up
