@littlescribe, just to answer this question you seem to be putting everywhere :)

STEEM is a currency on the steem blockchain, SBD is a currency on the steem blockchain, GOLOS is a currency on the steem blockchain.

DTube is a platform on the steem blockchain, Busy.org is a platform on the steem blockchain.

What is not is a platform on steemit.

It's like Microsoft has so many programmed built on it. It's like apps being built on the operative system.

That's the closest metaphor I can give and I hope this helps :)
