I think that added HNQs to the chat feed will be useful information to have now that there is an official way to determine and indicate this with the recent HNQ update.
This will raise awareness of questions as they hit HNQ and alert members of the community that are in the chat to help watch out for any signs that issues are arising and potentially help to mitigate (vote, flag, etc.) any issues that arise.
I think the most helpful way to implement it would be the same way that Oracle is in that the HNQs are posted One-box style in the chat feed as they hit HNQ status (as opposed to putting them in the upper left hand corner feeds).
Does this sound useful to anyone else?
