A digital map may provide information that is not only personalized to a particular user/viewer, but also is current and dynamic. In particular, a user may subscribe to news from a specific point of interest represented on the digital map (e.g., a restaurant, store, bar, museum, theater, park, etc.), and thereafter view associated posts/updates/news items for that point of interest. The digital map allows a user to subscribe to a particular point of interest by way of providing a user-selectable control on the map (e.g., near the point of interest). Once the user has subscribed, the digital map may display the latest news item/update for the point of interest each time the user’s viewport displays that point of interest. The news items may be provided by an authorized (e.g., registered) source, and may be updated as desired.
