Setup involves multiple steps like installing Cassandra, configuring virtualenv, and managing dependencies, which can be cumbersome and error-prone for quick learning.

Focuses only on basic Twitter functionalities (e.g., tweets and follows) without advanced features like direct messages, hashtags, or real-time notifications, reducing real-world applicability.

As an educational example, it likely lacks regular updates, community support, or documentation beyond the README, making it less suitable for evolving projects.
