Based on my knowledge as of April 2024, here's a general assessment of the Hive blockchain compared to the legacy Steem chain:
Governance: Hive has implemented more decentralized governance mechanisms, learning from the Steem takeover attempt. This includes changes to witness voting and stake-weighted voting systems.
Community: Hive retained a significant portion of the active Steem community, including many developers, content creators, and dApp projects. This has helped maintain a vibrant ecosystem.
