Clarify Thankful vision on landing page

[ErikBjare]

These things will help clarify how we differentiate from competition and hopefully get people more excited than the current somewhat low-information page.

• Crypto-agnostic
• Truly P2P donations
• Any type of content (video, music, podcasts, software)
• As easy as using Spotify or Netflix
• Recurring donations (replace Patreon with crypto)
• A way for supporters (Decide on terminology for creators and donors/supporters #3) to get acknowledged by creators (if they want to)

Even if some of these things will take a while it's important to signal the direction we want to go. Radical transparency.
