Hello, thanks for the kind words! Most of our POI data comes from multiple sources, including data agreements and our own scrapers. We have a few sources we like to "watch" who tend to be fairly accurate for things like openings and closings and have some heuristics to figure out if a place is actually closed. We also allow our users to flag places for review. It's definitely imperfect! I've had to manually research and close or "re-open" a few places over the past couple days as more people have had a chance to see our data in action. We're not tracking menus yet, but it's high on our list for things to tackle. Relocations will generally end up being a "new place" in our system. I'm hoping to make it so the "old location" redirects to the "new location" at some point. We're not there quite yet.
