I guess the few most important things to emphasize might be:
- A decentralized social media platform
- You own your account and your community
- Censorship resistance
- Platform revenue gets paid out to the users
They could be headings with a sentence of explanation under each one, elaborating that it's not owned by any corporation but by a worldwide community, that we have decentralized governance, etc.
Then, what are the calls to action? Perhaps a few:
- Register (leads to registration page - could be the largest-size option with the next ones smaller underneath it)
- Explore content (leads to curated or trending posts)
- Explore communities (leads to the communities page)
- Learn more (leads to more in-depth explanation: FAQs, Hive whitepaper, etc.)
There's my thoughts.
