Farcaster and other blockchain based social networks solve the problems inherent to existing, corporate social media platforms- 
Difficultly balancing free speech and censorship, prioritizing corporate interests over those of their users, and not allowing the creators who are generating all the value for these platforms to own their audience or their content.

When users own their identity and social graph, social network lock in goes away, so apps (like warpcast) have to work harder to retain users.

Decentralized social networks like Farcaster offer a solution to the issues of centralized platforms by empowering users to own their identity and content. This shift challenges the existing model and encourages platforms to prioritize user interests over corporate gains, ultimately fostering a more equitable and user-centric social environment.
