So would Medium allow a Steem article? Can I just write a post asking people why they are wasting their time here where there is an engaging user-base and monetary rewards issued both ways somewhere else?

I have no idea but I would assume that they wouldn't feature story it at least. :D

Fair enough, something like learning the most in the most difficult situations?

More just the day to day grind kind of stuff. Steem is far from the most difficult situations my life has seen. :)
