This poster summarizes a study analyzing tweets from the #agu10 hashtag during the 2010 American Geophysical Union meeting to determine if Twitter constitutes scholarly communication. The most prolific Twitter accounts were from institutional accounts like NASA and AGU. Common tweet types included live tweeting of sessions, coordinating meetings, and hallway conversations. While tweets showed information sharing and relationship maintenance, they likely don't replace all functions of in-person conferences. The study aims to better understand scientific communication on Twitter and compare findings to other conferences and blogs.
