With respect, no, Medium doesn't, and as a Boost nominator, I can see it in cold, hard stats. Medium is better than it used to be, definitely, but the feeds shown to readers are still dominated by listicles ("Ten Habits.., "Ten Things ...") and fluffy pop psychology and "life hacks" stories while too many detailed stories on serious topics are neglected--not Boosted and sometimes not even distributed.
Medium can be different from all the other Web sites out there by prioritizing meaningful content over entertainment. I still hope Medium will be bold and live up to its potential.
