Like past regimes, Sudan's government is trying to silence protests by periodically shutting off internet access. Activists have found a way to keep everyone informed, however, by launching the Abena Crowd Map. The tool sends SMS-based reports of demonstrations and other events to a crowdmapping platform where contributors verify, locate and post stories. Observers can both filter the report stream and get alerts when incidents take place within a given area. The map won't always help protesters on the ground, but it will share their ordeal with the outside world -- and prevent Sudan's rulers from controlling the narrative.
