Great initiative. I think that in order to be effective, those facts must be short and catchy, even if they don't convey the full picture.

• Wallet addresses as usernames.
• Free transactions, no fees.
• Fast transactions, 3 seconds transfers.
• Scalable: 100 000 transactions per second (as much as EOS, if not more).
• ROI on holding steempower (currently 2%, can be a lot more if delegating for a return or curating).
• Web app specific blockchain, which will keep it ahead of general smart contract blockchains.
• Self funded DAO, where Steem Power holders can vote what gets funded.
• Earn by posting, earn by curating (voting others' posts).
• Create a community on the blockchain, which is independent of the website on which it can be accessed. (You can even create your own website to access it).
• Launch (Airdrop or ICO) your own coin, with similar characteristics to Steem, with 0 programming experience.
• Integrate that coin into your community, or your web application (website).
• RC system ensures that an increase in users on steem will result in an increasing demand for Steem Power, causing price increase for Steem.
