What is the "hot" category topic sorting option?

Continuing the discussion from Discourse Version 2.9:

What will this feature be like? How will it work? What does it do? I couldn’t find a dedicated topic for it.

Also, I’m extremely curious as to why it’s being added to Discourse… :thinking:

Basically Discourse Hot Topics

I can’t wait to see that feature natively baked into Discourse! :partying_face:

Is it already available in a beta version of Discourse?
