Steemit's UI never was intended for people from Medium.
But we do have alternative UI's they just aren't here on steemit.com
That's kind of the point though. Integrating a steem backend into medium would be good for them and good for us, a total win/win.
Love the idea. Good luck! You will certainly need it, given the current state of play of this platform.
BTW not just the UI - there is a much deeper conversation on the 'fairness' and the propensity of only 'whales', half-naked (or fully) women, and sports to dominate this nascent platform. UI is HUGE; this is even bigger IMHO.
