Yup. There's a microblogging app (Twitter clone) called TentStatus, available hosted at https://tent.is, or run your own instance of the code: https://github.com/tent/tent-status. Several people are working on iOS and Android apps to support the microblogging use case.
Meanwhile, the inventors of Tent have 5 people working 60+ hours a week running Tent.is and developing the protocol and apps for it. They haven't revealed what's next, though it sounds like some non-status apps are in the works.
There's Essayist, a (very alpha) long-form blogging app, hosted at http://essayist.mndj.me, code at https://github.com/mwanji/essayist
