This study analyzes Twitter communications during the 2011 Egyptian revolution and January 25th demonstration. The researchers trace how Twitter communications developed over time and suggest a sequential crisis communication model of improvisation, verification, and solidification (IVS). An analysis of over 4,000 tweets from Egypt, other Arab nations, and non-Arab nations during the demonstration found that tweets from Egypt focused more on improvising information, tweets from non-Arab nations focused more on verification, and tweets discussing solidification of collective identity were evenly distributed. The IVS process showed how Twitter served as a global collective sense-making system through personal participation during the political crisis.
