What do you think of a global shoutbox/chat that is implemented as steem comments? One could even have a small 1% :black_heart: button next to each shout :thinking:
Announcement global pinning is a great idea, I will note that down.
If a chat box is implemented and on chain then it could eat up allot of RC. Which could he a huge hinderance to new players / players lacking RC. It might be best to have a chat box that isn't connect to STEEM comments. If it must be connected then I would 100% go with a shout box over a chat box.
