A Zillow commercial refers to their agents as a “neighborhood savant.” Are Zillow agents or realtors the best people to claim this title?

A real estate agent might know a lot about neighborhoods or communities. Looking at the local marketing realtors do, I see that they claim to know about different suburbs. In particular, they have knowledge about the local housing market through what has sold and what has not. They can also talk about other aspects of the community, such as schools and nearby amenities.
If I go to websites like Zillow or Realtors.com, they offer neighborhood information with each property listing. This includes a map, walkability scores, ratings of local schools, other nearby listings and recent sales, and more.
But what does it take to know about a neighborhood? Who can accurately describe what it is like to live there or how the character of a place plays out? Does anyone offer insights from local residents? Do real estate agents live in the communities they sell in or have secondhand information from local residents and organizations?
This reminds me of two posts I put together years ago on how to learn about a suburb. There are lots of sources of information about communities and some of it is available online. But some of it is not. Talking to people or walking through a community or reading local histories can provide some insights that are harder to intuit online.
Who else might be a “neighborhood savant”? A local journalist, where they are still available. A local political official or a longstanding member of a community institution. A local historian. Residents who take an interest in and actively participate in their neighborhood.
