Well the thing is even since before August there was a smart contract that came along with the EOSIO software that provided a very rudimentary shell of what STEEM does for people as an example if they were trying to build something like that. Then in Around October an example appeared on their github showing a rudimentary example of doing a similar thing utilizing DMUX which is a way to utilize a MongoDB instance to support faster access to the data that is being written in to the blockchain.
Then at the EOS hackathon in San Francisco I talked to Dan Larimer about how the Steemit community is excited about the next iteration of a Steem type blogging platform. He said that they were finalizing the key management aspects of it and a few other things.
It will likely happen fairly soon but I wouldn't get too excited about stuff potentially coming out tomorrow or anything. Likely it will be sometime in Q1 of 2019.
Block one has hired like 100 more people in the last couple of months so they have really ramped up their staff and what they are doing.
