The document introduces micro-volunteering as a way to engage people in volunteering through small tasks that can be completed in brief moments using digital tools and smartphones. It notes that while people say they don't have time to volunteer traditionally, collectively billions of hours are spent online each day watching videos, on social media, etc. Micro-volunteering breaks volunteering into small online tasks like tagging photos or transcribing documents that can add up to make a big impact. Nonprofits can leverage people's spare digital moments by posting micro-volunteering tasks online.
