People need to realize that STEEM is not a blogging blockchain only, STEEM is a cryptocurrency, and just like any other cryptocurrency it can be used to make dapps, games, supply chains, etc...

True, except for the "just like any other cryptocurrency" part, not all of them allow this kind of flexibility.

BTC is distributed to the people through mining, STEEM is through writing content (Proof-of-brain).

eehm that's imprecise to say the least. STEEM is distributed in 3 ways: first, the witnesses who "forge" the blocks get steem. Second, every vested user (i.e. users owning Steem Power) receive a cut of the inflation. And then finally we get to steem that is distributed throught upvotes. On steem we like calling that rewards from proof-of-brain, but this includes rewards from all upvotes, including self-upvotes, vote bider upvotes, etc. I would say some portion of steem is indeed distributed through "proof of brain", but certainly not all of it.
