RE: Muse in a nutshell from a purely crypto perspective
I wish Muse well but wonder that you are compounding niches.. openledger is a very confusing environment - perhaps that tempts fewer transactions; posting on Steem, then is equally obscure - it's not obvious where else updates are put to.. Steem certainly not my first choice.
Hopefully the reality of Muse will be not bound by the success of either openledger as an exchange or by posts to just Steem. Reddit or Bitcointalk etc will have a larger audience, even if the impact of a post is less obvious the footprint will catch new users rather than the usual crowd.
Good luck - will watch with interest.
