Design a cross-team way to share our successes and changes we've made to the site

sharing our successes cross team adds more energy into the community. everyone loves to feel part of something that has momentum, and also needs to know what’s going on outside of their channel.

some of those will be important for all users and should be site-wide announcements. others should be something users are aware of and can easily shift from their central experience to give feedback, congratulations, or comment on, but would irritate many users due to the high volume we will have in the near future, if it was central to their space.

create a #victorydance tag!

It would easy and convenient for users to post a tag. How would others see these? A live feed they are all subscribed too?
