Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.

For asking questions, see:

  • Stack Overflow with questions tagged "go"
  • The Go Forum, a web-based forum
  • Gophers Slack, use the invite app for access. The #general channel is a good starting point.
  • Go Community on Hashnode with questions and posts tagged with "go"
  • The golang-nuts mailing list
  • IRC channel #go-nuts on Freenode

If such a discussion concludes that this is a bug in Go, come back here and post a full issue report.
