Ushahidi members, a non-profit software company, funded by several foundations, work in their offices on January 17, 2013 in Nairobi. Five years ago, a handful of bloggers invented a way to track — and hopefully of preventing — bloody post-election violence that hit Kenya in which over 1,100 people were killed.The group of friends that set up Ushahidi — which means “to witness” in Kenya’s Swahili language — have seen their concept become a worldwide success, used in conflict and disaster zones, and again in Kenya ahead of March 4 polls.
