I would have a product recommendation. Twitter missed the change to be a player in the chat space, but it could still offer a chat experience that other services can't. Imagine Twitter would start offering users the possibility to create group chats where only the invited users can write in but that others could follow in real time. So lets say there is an Apple keynote and @BenedictEvans, @asymco and @gruber start a group chat where they comment the event. I get a notification that this group chat started and I can go and follow it (the same way I could follow a live video). I can't comment myself, but I can follow their conversation (and maybe hit the like button from time to time). Because it's a chat, the participants will write much more than they would if they would be only limited to tweeting. It's crazy that in 2017 we can see celebrities interacting with each other via video, tweets,snaps, Facebook comments and so on, but there is no option to follow a real time chat between them.
