Social media used to be all about assumptions: Who is online, what they are doing, how much they love you, whether or not your content resonates. When nonprofits and companies began rapidly adopting social media in the late 2000s, activities were based on assumptions and experimental ideas. Fast forward five years, and we now have at our disposal some solid measurement and data collection software systems, research studies, case studies, demographic data and a relatively savvy social media user base. The problem? We’re still working from hunches and assumptions.
