There's no point in rewriting it. This text is too overcomplicated. Not just servers but decentralized servers, not just posts but "notes and events", not just signatures but cryptographic signatures, etc.
What are events? What is cryptography? Aren't other servers decentralized? You write here that it's safe to trust your notes to strangers, but you need to start your relay to make it safe. WTF 🤣 Any member of the #zbd family will have a brain melt because of your text.
