We were considering enabling GitHub Discussions for questions and general discussions.
Any comments/thoughts?

[HumairAK]

I don't think GH issues should be for q/a.

Wouldn't having an issue template for a question only give the impression that we welcome q/a style gh issues?

I agree with sending such questions to GH discussions. Don't know too much about gh discussions, but it seems like for this we would want a category form: https://docs.github.com/en/discussions/managing-discussions-for-your-community/creating-discussion-category-forms instead of an issue template

Looking for your thoughts too

[Tomcli]

In the new projects we created, we use GitHub discussions because it works like a forum where you can upvote the important discussion. This also help reduce the number of issues we have.

Before GitHub discussions, the only way users can ask question is through issues and slack, so you still see some old GitHub repo is doing that way. I agree we should use GitHub discussions instead as many community such as KServe, Argo already using it.

not personally familiar with Discussions, but it seems like it will do the trick.

is it easy to enable?

[rimolive]

@gregsheremeta Easy peasy! Just check this option in repo settings.

From GH Discussions, you can even use categories for discussions, and create polls.

I love the idea of moving Q/A and generic discussion to GH Discussions. That will help in reducing the number of issues and keep them higher quality

[StefanoFioravanzo]

If we go with GH discussions, let's see if we can direct users to that when they try opening a new issue. See how they do it in JAX https://github.com/google/jax/issues/new/choose

@chensun Can you enable the discussions tab? I'll change the issues template to guide the community to that tab when enabled, following @StefanoFioravanzo suggestion.

EDIT: I went ahead and added the changes. When Discussions tab is enabled, we can merge this PR.

[chensun]

@chensun Can you enable the discussions tab?

Done.

@rimolive I will leave it to you to unhold and merge.
