Ditto.pub functions more as an aggregator and directory rather than a traditional intermediary or gateway. Here's a breakdown of its role:

1. **Aggregator**: Ditto.pub collects and organizes data from various Nostr relays. It indexes this information to make it easier for users to search and discover content.

2. **Directory**: It serves as a directory for Nostr profiles, events, and notes, providing a centralized interface for users to find and interact with decentralized content.

3. **User Interface**: While the data remains decentralized and distributed across multiple relays, Ditto.pub offers a user-friendly interface to access this data. It does not store or control the data itself but provides tools to navigate it.

4. **Non-Intermediary**: Unlike traditional intermediaries that might control or gatekeep access to information, Ditto.pub does not have control over the data. It simply provides a way to view and interact with data that is already available on the Nostr network.

5. **Non-Gateway**: It is not a gateway in the sense of being a single point of access or control. Users can still interact with the Nostr network directly through other clients and relays. Ditto.pub enhances the experience by making it easier to find and connect with content.

In summary, Ditto.pub enhances the discoverability and usability of the Nostr network without acting as a controlling intermediary or gateway, preserving the decentralized nature of the protocol.
