Unless you are looking to contribute to a project and kick off a project I would recommend sticking with the bigger players our there like nodebb/vanilla and so on. Getting stuff right is not easy, very few forum software platforms out there for example have a bug bounty like (https://hackerone.com/discourse https://hackerone.com/discourse ), last thing you want to do is deploy an XSS hive out there to the public. As far as I know there is no small-medium well supported Discourse alternative written in Go. There is a Slack alternative though written in Go called mattermost which I can recommend.
