Tbh, Microsoft shouldn't be developing the app anymore. Twitter can access the people hub too. Why aren't Microsoft giving the tools to Facebook instead. If they did thin the beginning, we wouldn't be missing out on features such as Facebook trends, news articles, apps linking to the Facebook app for game invites, searching for topics, smart search (search for people by city, address, place of work etc). At least we managed to get picture comments (in late 2014). With Windows 10, the APIs give all the developers the same tools Microsoft are allowed to use which means access to parts of the OS like the people hub, phone, calendar, Cortana interests, Xbox, accounts, emails etc. Just look at the ratings and reviews in the store. Microsoft shouldn't develop the app anymore. Facebook should.
