By: Mark Leon Goldberg on June 19, 2012 Rio+Social is happening now. You can watch it here. There will be some excellent speakers throughout the day from every corner of the globe, from heads of UN agencies like UNICEF and WFP, to social entrepreneurs and business entrepreneurs. This is the event of the week that I have been most looking forward to. They will be taking questions from the Twitterverse using the hashtag #rioplussocial. This kind of event tends to lend itself to live tweeting, which I’ll be doing @marklgoldberg and @undispatch.
