Laura Pasquini and I are working on analyzing #sachat data, a follow-up to work I’ve done previously but did not formally publish. Part of our work involves looking at a few other student affairs-related hashtags to help us understand #sachat in context. This figure shows the number of Twitter messages posted with particular hashtags – #highered, #sachat, #sadoc, #sagrad, #sajobs, and #studentaffairs – during the week of June 27, 2011. The #sachat session really stands out here both in the number of messages posted and in how it interrupts an otherwise regular daily and weekly pattern. This isn’t a profound discovery but it’s an easy way of illustrating that #sachat sessions are relatively unique and prominent uses of Twitter among some users.
