This document discusses how social media and internet technologies are changing citizen participation in government. It outlines different models for e-government and levels of e-participation, from governments using social media at basic levels to more advanced models like open data and crowdsourcing that facilitate direct collaboration between citizens and policymakers. While many Western governments have adopted social media, overall internet access and bandwidth globally remain unequal. Fully realizing 21st century e-participation requires openness, transparency and accountability through transforming government with information and communication technologies.
