On: You can now set your status on GitHub

Likewise, this could be a useful feature in the context of enterprise GitHub or private repos used by organizations. Seeing the current status of a coworker without leaving GitHub is a nice plus, especially if they start integrating statuses with tag autocompletion.

Indeed I can see that they are quite close to Slack's own default statuses.

Now if they just evolve their "discussions" (formerly issues) into "live discussions", and then add one more feature to allow separating it by "tag" or maybe "topic" per repo, they can pretty much replace Slack.
