It's important to add info about communities.
What are they? How to create one? Can they be accessed through multiple frontends? Can they be tokenized?

That's a good segway into hive engine: What is Hive-engine? What is a side-chain? Are there other side-chains being worked on? Are there smart contracts on hive or just sidechains? How do I launch my own coin? How do I launch a coin and tie it to my community?

More generally, I think it would be good to focus less on the pure blogging aspect of hive and more on the fact that it can be used as a layer 1 to decentralize different kind of apps.

Gaming dapps should be covered, and the way they work. What is a custom_json? How can it be used to decentralize a gaming dapp? Smart contract vs custom_json? Is it possible to create NFTs on hive?
