Twitters health will be built and measured by how we help encourage healthy debate, conversations, and critical thinking. By measuring our contribution to the overall health of the public conversation, we believe we can more holistically approach and measure our impact on the world for years to come. Cortico, a non-profit research organization, has spent time to more deeply understand the concept of measuring conversational health and developed four indicators to measure it: shared attention, shared reality, variety of opinion, and receptivity. Twitter expects to announce the first selected projects in July.”]
