I think the biggest blocker with using publicly available datasets is stale data.

If you, or anyone else who aggregates these datasets could make it EASY to find the FREQUENCY of updates, rather than just the LAST UPDATED timestamp, it'd incentivize people to consume APIs more.

I realize having a snapshot from 2014 is better than what was publicly available before. But I feel no one's really talked about why they would or wouldn't use particular data.
