A computer-implemented method provides a real-time participatory experience of localized event information. In one embodiment, the method includes receiving over a communications network a collection of messages, each message involving a localized event and storing messages of the collection. With respect to each message of the collection, the method further includes extracting an identity of the sender from the message, and updating a user database based on the sender's identity; parsing the message to derive a location from the message about the event; storing in an event database the derived location in association with the event; retrieving, from a user database, a list of users and notification parameters; and generating a contemporaneous alert reporting on information stored in the event database and causing the alert to be sent over the communications network to the users on the list in accordance with the notification parameters.
