Some like to poke fun at Facebook for making several impressions on our devices. We’ve got Messenger, Instagram, Facebook, Paper (for iPhone users, at least), WhatsApp — it’s a lot. At their “Analyst Day” soiree, Twitter is teasing that they may do just the same. Executives at Twitter told analysts they were working on improving their direct messaging service, and were very high “applications that can live outside of Twitter”. The microblogging platform may also get a “best of” feature to show you what cool things you might have missed, and will get some interesting video features.
