With the launch of South Africa’s new civil society organisation Corruption Watch in Johannesburg on 26 January, the hashtag #corruptionwatch became the second-highest trending topic in South Africa on Twitter. Hundreds of tweets were sent out from the launch itself at Constitution Hill, mainly from journalists such as City Press editor Ferial Haffajee, New York Times Johannesburg bureau chief Lydia Polgreen and Eyewitness News reporter Alex Eliseev. But many other ordinary South Africans added their voices to the microblogging site’s Corruption Watch conversation. Here’s a selection of the day’s top #corruptionwatch tweets.
