I agree that we shall not run too quickly and change the whole Steem/SP model. BUT, in my view Steem requires more services and apps quickly to be able to stay relevant. I do not believe Steem can survive only with blogging services. I have the fear that the way SP is implemented today, it'll prevent others from selecting Steem as the currency for their services. I can tell you, I have an idea already for some time for a service using a non-FIAT currency, and I'm here to understand how Steem/Steemit works to see if Steem can be that currency. I cannot come to a conclusion yet, but thus far, Steem seems to be a bit too chaotic to build a service on which shall feed people (read: employees) mouths.
