This is one of the reasons I want to allocate time at some point to setup a relay to capture posts for indexing. Sure there's plenty noise, but the textual content can provide signal.

Locally I want to retain my data and relationships and be able to search past messages. It would be useful for CRM tool integrations for example, seeing the reach of what your customers interact with for possible future customers.

In a prior life I worked on systems that scraped news sources and articles to try to detect social and health anomalies to predict where other downstream events would occur or alert for thresholds. Every data source like nostr can provide a wealth of information.
