A research project by John Conroy, a Masters student supervised by Josephine Griffith at NUI Galway, has gathered some interesting statistics on Twitter usage and the most tweeted users in Ireland (during February / March 2010).
The study acquired 307,168 tweets from a group of Irish Twitter users. These tweets yielded 93,022 resolvable replies (@someuser), and another 7,298 retweets. Therefore, a third of the tweets investigated contained either a reply to another user or a retweet. Of the 93,022 resolvable replies, the vast majority were directed at users external to the Irish group. 15,364 replies (16.5%) were directed at an Irish user, and 77,658 (83.5%) at a user outside of Ireland. (Just over 2,000 investigated tokens were spoiled, often due to typos or e-mail addresses being detected as replies.)
