It's crap. Steem blockchain is just another iteration of Dan Larimer's Bitshares. It is also almost the same thing as EOS. Larimer keeps making new blockchains out of the old ones to cash in every time. Why can't he just integrate every feature into one chain?
Dan left steem for a long time, he is nothing to do with it now. It's existing blockchain and improved by the steemit team and witnesses. Eos is not that good for social applications. It's really hard to create a wallet in eos or to use it. They kind want to create a social application, but it was never created, even if it will be it will not compete with steem !
So, steem has nothing to do now with eos. It's a great blockchain in term of proof of brain and it's much better than facebook or instagram or any other social media where we earn nothing by sharing our information that they use to sell.
If you know a better social blockchain tell me about it.
