Tube videos while in mid chat. Have you ever tried to recommend a friend to install an app in Google Play. How amazing would it be to see that link converted into an install button with a short description? I hate email - We all hate it, and we all want it to go away. Maybe this is an area where Twitter can make some inroads. Facebook is updating messenger to work with business during the checkout flow. I still do a tremendous amount of talking via email. Being able to subscript to individual updates to get pushed to your phone. Impromptu conversations - There is a lot of times when I shared links in twitter and sent an email or add a new text or hangouts. It would be nice to have this instant sharing and conversations develop over a topic. If someone is talking about something in their public feed easily being able to bring that conversation into a private or small group setting could be interesting to see unfold.
