Nice post. One thing you mentioned is there needs to be an app. There are a few apps but I think the one that is most prominent is esteem. Although it is still young, like steemit, it is being improved all the time.
I use esteem a bit but I am much more comfortable with using steemit on chrome on my phone as it pretty much works like an app. I just made a shortcut to my steemit home page and open that like I'd open any other app on my phone.
