A good mystery is hard to find. Just a screenshot.
UPDATE: (as of June 25, 2012)
A story on rappler.com (dated June 3, updated June 18, 2012) gives some details about the board members of Rappler. This seems to suggest that rappler is a corporation. It appears, but is not quite clear from the story, that the shareholders are either the corporate entities of Newsbreak, Hatchd, and Dolphin Fire, or their principals.
Hatchd, in its website, acknowledges that it is “the business and technology arm” to Rappler. It has an office in the Philippines, and appears to sell advertising packages that appear at the Rappler site.
There was a story in March this year, also by Rappler, that the businessman, Manuel Pangilinan, was interested in acquiring a “very small” stake in Rappler.
